Question

The tension in a string from which a 4.0-kg object is suspended in an elevator is equal to 44 N. What is

the acceleration of the elevator?

Answer 1

Explanation:

the answer to the question is 1.2 m/s2 upward

Answer 2

Answer :

If the tension in a string strung in an elevator from which a 4.0-kg object is suspended is 44 N. The accelerator then advances at a rate of 1 m/s².

Explanation:

Given : tension (T) = 44 N        

              Mass (M) = 4 kg

In an elevator, a string is suspended and moving with an acceleration (a) that must be determined.

We can achieve this by balancing the equations of motion.

force = T - mg    

 ma = T- mg

  4a = 44 - 4 × 10    

  4a = 44- 40

   4a = 4    

 a = 1m/s²

Hence elevator moves with acceleration  1m/s².
