A ball is thrown with a speed of 17.0 m/s from the top of a cliff 9.00 m high as shown in the figure below. With what speed does the ball hit the ground? 17.0 m/s 9.00 m

A football punter wants to kick the ball so that it is in the air for 4.0 s and lands 50 m from where it was kicked. a. Skecth the path of the football showing horizontal and vertical components of velocity throught it's path on the same diagram. Label all important parameters in the diagram. b. At what angle and with what initial speed should he kick the ball? Assume the ball leaves 1.0 m above the ground. Show all work neatly. Posted Today at 8:48 pm

A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. The cabinet starts from rest. What is the final kinetic energy of the cabinet at the end of the ramp, in Joules? Use g = 10.0 m/s2.  Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

This golfer has been known to tell some extraordinary stories. Explain if each situation is possible using conservation of energy. Assume friction/air resistance ARE present. They hit a ball in a completely flat field, and the ball followed a parabolic trajectory (like in projectile motion). They measured the ball speed at takeoff to be 91m/s. When the ball landed 145m away, they measured their ball speed on landing to be 94m/s.  They hit the ball along the ground. When the ball left the club, it was moving at 2m/s. When the ball went in the hole, it was moving at only 0.9m/s. The golfer claims that hitting the ball with a club that is four times as massive at the same speed makes the ball go two times faster off the tee. Note: Please solve the subparts
