A particle moves on a circular path with constant speed 15 m/s. Find the change in speed & magnitude of change in velocity, when particle completes half revolution:

Open in App

Solution

After Half revolution,
Change in speed $= 15 - 15 = 0 m / s$
Change in velocity $= 15 - (- 15) = 30 m / s$

A particle moves on a circular path with constant speed 15 m/s. Find the change in speed & magnitude of change in velocity, when particle completes half revolution:

After Half revolution, Change in speed =15−15=0m/sChange in velocity =15−(−15)=30m/s

After Half revolution,
Change in speed $= 15 - 15 = 0 m / s$
