Question

A particle of mass 2 kg moves ona circular path with constant speed 10m/s.Find change in speed and magnitude of change in velocity.when particle completes half revolution

Answer 1

Hey dude here's ur answerAfter completing half revolution, particle speed remains constant so change in speed will be 0 m/sec, but there is change in velocity vector... Both have same magnitude but opposite directions, so magnitude of change in velocity will be 20 m/sec
Hope it will help you.
