The fastest served tennisball, served by "Big Bill" Tilden in 1931, was measured at73.14 m/s. The mass of a tennis ball is 57 g, and the ball is typi-cally in contact with the tennis racquet for 30.0 ms, with the ballstarting from rest. Assuming constant acceleration, (a) what forcedid Big Bill's tennis racquet exert on the tennis ball if he hit itessentially horizontally? (b) Draw free-body diagrams of the tennisball during the serve and just after it moved free of the racquet.

A 63.0 kgkg parachutist falling vertically at a speed of 6.50 m/sm/s hits the ground, which brings him to a complete stop in a distance of 0.87 mm (roughly half of his height). 1) Assuming constant acceleration after his feet first touch the ground, what is the average force exerted on the parachutist by the ground? Express your answer with the appropriate units.

Superman must stop a 120-km/h train in 200 m to keep it from hitting a stalled car on the tracks. If the train’s mass is 3 X 105 kg, how much force must he exert? Compare to the weight of the train (give as %). How much force does the train exert on Superman? Solution in handwritten.
Two constant forces of magnitudes F1 and F2, act on a particle of mass 5.00 [kg] which is at rest at the origin. The force F1 points at 14.5° west of north, while the force F2, points at 58.3° west of south. Due to the two forces, the particle accelerates and is later located at 32.4 [m], 17.0° north of west with speed 12.2 [m/s]. What is F1?
