A ball is thrown with a purely horizontal velocity of 25m/s at a wall which is 15m away. The ball is thrown at a height of 1.6 m above the horizontal terrain. The ball has a coefficient of restitution of 0.75. After the ball impacts the wall and bounces off the wall back toward the thrower, how far from the wall will the ball initially strike the ground?

A ball of soft clay with mass 1 kg falls from a height of 10 m starting at rest. When the clay hits the ground it flattens and comes to a stop. Which of the following is true? Gravity does work on the ball equal to 980 J, and all this energy is dissipated during the deformation of the ball on impact. Gravity does work on the ball equal to 98 J, and all of this energy is dissipated during...
A baseball is thrown at an angle = 21° above the horizontal with an initial vertical velocity v0y = 9.75 m/s
A baseball is thrown at an angle = 21° above the horizontal with an initial vertical velocity v0y = 9.75 m/s. Use a Cartesian coordinate system with the origin at the baseball's initial position.Part (a) Create an expression for the ball's initial horizontal velocity component, v0x, in terms of v0y, sin(θ), and cos(θ).Part (b) Calculate the initial horizontal velocity component, v0x in m/s. Part (c) Find the ball's initial velocity magnitude, v0 in m/s.

A racquet ball with mass m = 0.252 kg is moving toward the wall
at v = 18.2 m/s and at an angle of θ = 25° with respect to the
horizontal. The ball makes a perfectly elastic collision with the
solid, frictionless wall and rebounds at the same angle with
respect to the horizontal. The ball is in contact with the wall for
t = 0.06 s.
