It takes the elevator in a skyscraper 3.6 s to reach its cruising speed of 11 m/s. a 62 kg passenger gets aboard on the ground floor.
what is the passenger's weight before theelevator starts moving?

Weight of the passenger will be 607.6 N

Explanation:

We have given that a elevator takes 3.6 sec to reach its cursing speed

So time t = 3.6 sec

Velocity v = 11 m /sec

Mass of the passenger m = 62 kg

We have to find the weight of the passenger weight before elevator starts moving

Before the elevator starts moving

So weight of the passenger will be equal to

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
