Question

A force of 500 dyn is applied against the motion of a body of mass 50g moving at 1 ms-1 when and where will the body stop. ​

Answer 1

letassune that the body is moving in x axis with initial speed u than the force F is applied against its motion applied such that it will stop after travelling distane s in t interval of time

u=1m/s v=0m/s

net force 500 dyn

so s= it + 1/2at×t so s=10 m and t= 10 sec
