A volleyball player throws the ball with an initial velocity that makes an angle ?= 35º with the horizontal. Determine: The magnitude of minimum initial velocity with which the ball must be thrown in order to pass the net of height h. More data: h= 2.40 m Y= 2.15 m L= 12 m

6. A ball was thrown straight upward and after 1 second it reaches its maximum height then it does free fall motion for 2 seconds. Calculate the following: (a) The maximum height reached by the ball. (b) The velocity of the ball before it reaches the ground. (g=10m/s²)

Current Attempt in Progress A ball with mass m kg is thrown upward with initial velocity 15 m/s from the roof of a building 19 m high. Neglect air resistance. Use g = 9.8 m/s². Round your answers to one decimal place. (a) Find the maximum height above the ground that the ball reaches. Xmax = meters (b) Assuming that the ball misses the building on the way down, find the time that it hits the ground. tend = i S eTextbook and Media Save for Later Submit Answer Using multiple attempts will impact your score. 10% sco duction after attempt 1 Attempts: 0 of 3 used

The following diagram shows a crate on an incline. The coefficient of kinetic friction (uk) between the crate and the incline is 0.1. The velocity of the box is zero, at which point in time it is subjected to a constant horizontal force F= 20 N. Determine the crate's velocity two seconds later. Weight of crate = 137 N %3D 20
