Question

A body describe a semicircular path of radius 7m in 11s .Find the speed and magnitude of velocity of the body​

Answer 1

Answer:

Radius =7m

time= 11s

then,distance=22/7= 22m

and displacement=2×7=14m

•

• • Speed = 22/11= 2 m/sec (speed= distance/time)

and velocity=14/11 m/sec(velocity = displacement/time)
