A particle of mass 2 kg moves on circular path with constant speed 10 m/s. When particle completes half revolution, find change in speed and magnitude of change in velocity.

Text Solution

Verified by Experts

Change in speed
` Delta v = 10 - 10 =0`
Change in velocity
`Deltavecv= vecv_l - vecv_i`
`= 10 hatj - (-10hatj) = 20 hatj`
Magnitude `|Delta vecv| = 20 m//s`
