Question

CA 1s SP6. A 60-kg man is in an elevator that is accelerating downward b. What is the net force acting on the man required to pro- c. What is the force exerted on the man's feet by the floor SP7. A at the rate of 1.4 m/s2 a. What is the true weight of the man in newtons? res tio ve 10 a. all. duce the acceleration? of the elevator? d. What is the apparent weight of the man in newtons? (This is the weight that would be read on the scale dial if the man were standing on a bathroom scale in the accel- b. c. d. 1s on erating elevator.) e. How would your answers to parts b through d change if the elevator were accelerating upward with an accelera- ing tion of 1.4 m/s2? rce

Explanation / Answer

a)

W = true weight = mg

W = 60 x 9.8

W = 588 N

b)

Fnet = net force = ma = 60 x 1.4 = 84 N

c)

Fn = force on feet by elevator in upward direction

W = weight in downward direction

force equation is given as

W - Fn = ma

588 - Fn = 84

Fn = 504 N

d)
