Projectile Motion I think I need some equations

• ch3570r
In summary, it takes the time it takes for the ball to fall (t) and multiply it by the velocity (v) to find the distance the ball will travel.

Im trying to figure out this problem, but I am not sure if I have the equation(s) I need.

"A ball is thrown horizontally out the window of a building with a velocity of 8.0 m/s from a height of 2500 m. How far from the base of the building will the ball land?"

a) 54 m
b) 60 m
c) 90 m
d) 115 m
e) 180 m

The equations I have for the X value (distance in X) include the following:
Vx = ▲x/▲t
▲X = V0 * ▲t
Vfx^2 = Vix^2

Is this all I need to find the answer? Or am I missing some equation(s)?

Sorry for the TRIPLE posts...my browser was going crazy

Find the time it takes to fall using a kinematic in the y direction and then use that to find distance in the xEDIT-wrong thread, someone else answered though

1. What is projectile motion?

Projectile motion refers to the motion of an object that is projected into the air and then follows a curved path due to the influence of gravity.

2. What are the key equations for projectile motion?

The key equations for projectile motion are the equations of motion, which include the equations for displacement, velocity, and acceleration in the x and y directions. These are:
- Displacement: Δx = v0t + 1/2at2
- Velocity: v = v0 + at
- Acceleration: a = g = -9.8 m/s2 (in the y direction)

3. How do you calculate the range of a projectile?

The range of a projectile is the horizontal distance it covers before hitting the ground. It can be calculated using the equation R = v0cosθ * (2v0sinθ/g), where v0 is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

4. What factors affect the trajectory of a projectile?

The trajectory of a projectile is affected by several factors, including the initial velocity, launch angle, air resistance, and the force of gravity. The shape and weight of the object can also play a role.

5. How is projectile motion used in real life?

Projectile motion is used in many real-life applications, such as sports (e.g. throwing a ball), fireworks, and even in space travel. Understanding projectile motion can also be useful in fields such as engineering and physics, where the motion of objects is analyzed and predicted.
