A particle of mass 2 kg moves on a circular path with constant speed 1

1.	A particle of mass 2 kg moves on a circular path with constant speed 10 m/s. Find change in speed and magnitude of change in velocity. When particle completes half revolution.Please help me to find the answers quickly. Don't go for the points.
Answer» Answer: After 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

Answer:

After 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
