|| BIO Human biomechanics. The fastest served tennis ball, served by Samuel Groth in 2012, was measured at 73 m/s. The mass of a tennis ball is 57 g, and the ball is typically in contact with the tennis racquet for 30.0 ms, with the ball starting from rest. Assuming constant acceleration, (a) what force did Groth’s tennis racquet exert on the tennis ball if he hit it essentially horizontally? (b) Make a free-body diagram of the tennis ball during the serve and one just after it has moved free of the racquet.

By itself, the 2500-kg pickup truck executes a 0-100 km/h acceleration run in 10 s along a level road. If the unit uniformly accelerates from rest to a speed of 25 m/s in a distance of 150 m, determine the tension T in the towing tongue OA. Neglect all effects of the 5° tongue angle, i.e., assume that OA is horizontal.
