Question

a mass of 50 kg was moving with a velocity of 400 metre per second a force of 40000 newton is applied to the mass and its velocity is reduced to 50 metre per second after sometime

Answer 1

Explanation:

A force of 40000 N is applied on the mass and its velocity is reduced to 50 m/s after some time. What is the distance ... a = change of velocity /t. or, t = change of velocity/a = 350/800 sec ...
