Question

2) A 60.0-kg person rides in elevator while standing on a scale. The elevator is traveling downward but

slowing down at a rate of 2.00 m/s2. The reading on the scale is closest to

A) 589 N.

B) 708 N.

C) 469 N.

D) 120 N.

Answer 1

Answer #1

ma = N - mg

(60.0 kg) * (2.00 m/s^2) = N - (60.0 kg) * (9.81 m/s^2)

N=708N

Consider a 77.0-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.08 m/s in 0.900 s. It travels with this constant speed for the next 5.00 s. The elevator then undergoes a uniform acceleration in the negative y direction for 1.70 s and comes to rest. (a) What does the spring scale register before the elevator starts to move? N (b) What does the spring scale register during...
