HNES 368 Practice Problems for Chapter 4 These practice problems are due by Tuesday (3/29/22). You must show your work to receive credit. Problems turned in past this date will receive half credit. You may do this with one other person from class. 1) You are throwing a 5 kg medicine ball back and forth to a training partner. You exert an average horizontal force of 100 N and move the medicine ball through 1.2 m of horizontal displacement. The medicine ball's initial velocity was zero; how much work did you do to the medicine ball and what was the velocity of the medicine ball at the instant of release? (2 points) work done ; 1205 : 3 ( 5kg) ( ve)" WJ (100 N) ( 1.2 mm) 120 5 2.5 kg ( vr ) ? 120 16, 93 m /s = yo 2) You are doing some plyometric training with a client. You are having her do depth jumps from a 1 m platform. If her mass is 60 kg, what is her gravitational potential energy as she steps off of the platform? (1 point) PE : (588. 6 N) (1m) PE : Wh :588. 6 31 3) If a tendon is stretched 8 mm (.008 m) and the stiffness of the tendon is 12,000 N/m how much strain energy is the tendon storing? (1 point) SE: 3 ( 12,000 N/m ) (1008 m ) (SE : . 384 )) 4) A client that you are personal training wants to know how much power he generates during the up/concentric phase of his squat exercise. If he is lifting 180 kg, from the bottom of his squat until he is standing is 1 m, and it takes him 2 seconds to complete the squat, what was his P = Work average power output? (1 point) time P = (176 5. 8 N (1 m) : 882.9 W/ 2 s 5) What was your client's power output in horsepower? (1 point) 746 W : 1 horsepower P = 1.18 horsepower
