Question

An elevator suspended by a vertical cable is moving downward but slowing down. The tension in the cable must be greater than the weight of the elevator. less than the weight of the elevator. equal to the weight of the elevator. A bucket is being lowered by a very light rope with a constant downward velocity. The tension in the rope must be equal to the weight of the bucket. greater than the weight of the bucket. less than the weight of the bucket. You push on box G that is next to box H, causing both boxes to slide along the floor, as shown in the figure. The reaction force to your push is the push of box G on box H. the push of box H on box G. the push of box G against you. the upward force of the floor n box G. the acceleration of box G A small car and a large SUV are at a stoplight. The car has a mass equal to half that of the SUV, and the SUV can produce a maximum accelerating force equal to twice that of the car. When the light turns green, both drivers push their accelerators to the floor at the same time. Which vehicle putts ahead of the other vehicle after a few seconds? the car pulls ahead. The SUV pulls ahead. It is a tie

Explanation / Answer

23)
A) greater than the weight of the elevator

Fnet = m*g - T

m*a = m*g - T

==> T = m*g - m*a

here a is negative so, T is greater than m*g
24)

A) equal to the weight of the bucket.

Fnet = T - m*g

m*a = T - m*g

0 = T -m*g

==> T = m*g

25) C) the push of box G against you

26) it is tie
