Volleyball Definition and 20 Threads

First I calculated the y component of the initial velocity vector: vy1 = 8.5 m/s * sin32 = 4.7 m/s next the change in distance Δd = d2 - d1 = 3.6m - 1.4m = 2.2m Then I put these numbers into the equation v2y^2 = v1y^2 + 2aydy v2y^2 = (4.7 m/2)^2 + 2(-9.8 m/s^2)(2.2m)...

Homework Statement A regulation volleyball court is L = 18.0 m long and a regulation volleyball net is d = 2.43 m high. A volleyball player strikes the ball a height h= 1.98 m directly above the back line, and the ball's initial velocity makes an angle θ = 39° with respect to the ground (see...

I've been bothered about this for a while now. As a volleyball player, I am constantly looking for ways to increase my vertical. So, my question is: Will an increase in muscle mass decrease my vertical? On one hand, I am getting stronger and therefore should be able to push harder off the...

Homework Statement A player hits a volleyball when it is 4 ft above the ground with an initial vertical velocity of 20 ft/s (equation would be h = -16t2 + 20t + 4). What is the maximum height of the ball? Homework Equations quadratic formula The Attempt at a Solution t = -20 ±√202 - 4(-16)(4)...

hi! i don't quite know how to start solving for this. i understand the problem and what it's asking for but i have no idea how to start solving for it. In a volleyball game, a player from one team spikes the ball over the net when the ball is 10 feet above the court. The spike drives the ball...

can someone explain to me how to start on this problem A volleyball is spiked so that its incoming velocity of +4.1 m/s is changed to an outgoing velocity of -18 m/s. The mass of the volleyball is 0.44 kg. What impulse does the player apply to the ball?

Homework Statement A regulation volleyball court is L = 18.0 m long and a regulation volleyball net is d = 2.43 m high. A volleyball player strikes the ball a height h = 1.73 m directly above the back line, and the ball's initial velocity makes an angle theta = 40 degrees with respect to the...

Homework Statement A sand volleyball player attempts a jump serve. The player is 9.0 meters away from the net, which is 2.43 meters high. If the volleyball player hits the ball at the top of his jump (where the ball is 3.25 meters above the ground) and hits it an angle of 2 degrees below the...

Why while playing volleyball after the ball passes the net it shows some abnormal motions?

Homework Statement A ball is traveling horizontally over a volleyball net when a player "spikes" it, driving it straight down to the ground. The ball's mass is 0.20 kg, its speed before being hit is 6.4 m/s and its speed immediately after the spike is 21 m/s. What is the magnitude of the...

Homework Statement A volleyball hit into the air has an initial speed of 10. meters per second. Which vector best represents the angle above the horizontal that the ball should be hit to remain in the air for the greatest amount of time? 1)90 degree above horizontal 2) 60 above...

[b]1. For women's volleyball the top of the net is 2.24m above the floor and the endline is 9.00m from the net. Using a jump serve, a player strikes the ball at a point 3.00 m above the floor and 8.00m (horizontally) from the net. If the initial velocity of the ball is horizontal and directed...

Homework Statement A regulation volleyball court is L = 18.0 m long and a regulation volleyball net is d = 2.43 m high. A volleyball player strikes the ball a height h = 1.81 m directly above the back line, and the ball's initial velocity makes an angle theta = 48° with respect to the ground...

Homework Statement In order for a volleyball player to jump vertically upward a distance of 0.8 meters, his initial velocity must be?Homework Equations s=v0t + .5at2 vf= v0 + atThe Attempt at a Solution I missed the question the other day on a practice and it has been forever since I messed...

OK I have 1 more question for today... Homework Statement A 0.45kg volleyball travels witha horizontal velocity of 3.2m/s over the net. You jump up an hit the ball back witha horizontal velocity 7 m/s. If the contact time is 0.047s, what is the average force on the ball? Homework...

Homework Statement A regulation volleyball court is L = 18.0 m long and the net is d = 2.43 m high. A volleyball player strikes the ball a height h = 1.61 m directly above the back line, and the ball's initial velocity makes an angle θ = 49° with respect to the ground. At what initial speed...

Homework Statement Jason hits a volleyball so that it moves with an initial velocity of 6.0 m/s straight upward. If the volleyball starts from 2.0 m above the floor, how long will it be in the air before it strikes the floor? Homework Equations y=-2.0m,Vi=+6.0 m/s a=-9.81m/s^2...

A regulation volleyball court is L = 18.0 m long and a regulation volleyball net is d = 2.43 m high. A volleyball player strikes the ball a height h = 1.52 m directly above the back line, and the ball's initial velocity makes an angle q = 55° with respect to the ground. At what initial speed...

Below is a question I will need to know well for my exam coming up. I don't even know where to start or what the steps are? I am very overwhelmed here...:eek: A volleyball spike begins with the arm overhead, the shoulder and elbow are flexed and the wrist is hyperextended. The upper arm...

in a theterball when the ball hits the stick where does the kinetic energy of the volleyball go? my educated guess is that is transformed into Earth's rotation
