# A classical mechanics problem by Kishor Neupane

**Classical Mechanics**Level pending

A force applied to a body of mass 0.5kg for 2 sec which is moving with velocity of 8m/s changes the direction of motion by angle of 60 degree.the force is?

A force applied to a bodyof mass 0.5kg for 2 sec which is moving with velocity of 10m/s 37 degree north of east changes the velocity finally to travel along north.the force is?

my teacher said q no 1. cannot be solved using components but q no 2 can be solved using components.why is that and please give the solutions to the problems please. Thank you!

ans given is for both questions which is same.
