Homework Statement
Neglecting air resistance, if you throw a ball straight up with a speed of 20 m/s, how far will it be moving when you catch it?
Homework Equations
None
I did mean how fast. Please excuse my typing error.SteamKing said:Do you mean how fast will it be moving when you catch it?
Are you sure there are no relevant equations to help you solve this problem? Did you give up while writing this post?
Projectile motion neglecting air resistance is a type of motion that occurs when an object is thrown or launched into the air without any external forces acting on it, such as air resistance. This type of motion is often studied in physics and can help us understand the behavior of objects in motion.
Air resistance can affect the motion of a projectile by slowing it down and changing its trajectory. This is because air resistance acts as a force that opposes the motion of the projectile, causing it to lose energy and change direction.
The formula for calculating the horizontal distance of a projectile is d = v*cos(θ)*t, where d is the distance, v is the initial velocity, θ is the launch angle, and t is the time in flight. This formula assumes that air resistance is negligible.
The maximum height of a projectile can be calculated using the formula h = (v*sin(θ))^2 / (2*g), where h is the maximum height, v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity. This formula also assumes that air resistance is negligible.
The angle of launch can greatly affect the motion of a projectile. Changing the angle can change the distance and height the projectile travels, as well as its overall trajectory. A higher angle will result in a longer flight time and a lower angle will result in a shorter flight time.
