Question

A force is applied to a mass of 16kg for 3sec As the force is removed the mass moves 81 meter in 3 sec . what was the value of the force applied ​

Answer 1

Explanation:

The value of the force applied is 144 N.

v = 81 m /3 s = 27 m/s. Since mass moves in 3 s is 81 m when the force removed. Therefore, the mass moves with uniform velocity (no acceleration) for next 3 s. F = 144 N
