Question

You are in an elevator that is accelerating you upward at 4.55 m/s^2. How much time does it take you to reach a speed of 11.0 m/s?​

Answer 1

t = 2.01 seconds

Step-by-step explanation:

It is given that,

The acceleration of the elevator is 4.55 m/s².

We need to find time taken by you to reach a speed of 11 m/s

The initial velocity of the person is equal to 0 (at rest). Let t is the time.

Using equation of kinematics as follows :

v = u +at

Acceleration = g-a and u = 0

So,

`t=(v)/(g-a)\\\\t=(11)/(10-4.55)\\\\t=2.01\ s`

So, 2.01 seconds is taken to reach a speed of 11 m/s.
