A ball player hits a home run, and the baseball just clears a wall 21.0 m high located 150.0 m from home plate. The ball is hit at an angle of 34.0° to the horizontal, and air resistance is negligible. Assume the ball is hit at a height of 1.0 m above the ground and that upward is positive. (a) What is the initial speed of the ball?

(b) How much time does it take for the ball to reach the wall?

(c) Find the velocity components of the ball when it reaches the wall.
m/s (x-component)
m/s (y-component)

Find the speed of the ball when it reaches the wall.

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
