dynamics. collisions Problem 10.3 A basketball impacts a metal surface as shown below. If the initial velocity of the basketball was 3 ft/s straight down and the coefficient of restitution is .85, what is the expected speed and direction (0) of the ball after the impact? V- 3 ft/s 250 (Solution : v 2.64 ft/s, θ = 36.25°) e-O.8
Vi = 8 ft/s 3 ft The girl throws the ball with a horizontal velocity of v, = 8 ft/s. If the coefficient of restitution between the ball and the ground is e = 0.8. determine the velocity of the ball just after it rebounds from the ground and the maximum height to which the ball rises after the first bounce.
1. The problem statement, all variables and given/known data a ball is thrown straight down from the top of a 220 feet building with an initital velocity of -22ft/s. What is the velocity of the ball after 3 seconds? What is the velocity of the ball after falling 108 feet? 2. Relevant equations s(t) = -16t^2 + Vi(t) + si vi = initial velocity, si = initial position 3. The attempt at a solution s(t) = -16t^2 +Vi(t) +si =...
