Question

a body completes a semicircle of radius 7m in 5sec the displacement of body ​

Answer 1

Explanation:

the velocity is given as

v = displacement / time

here,

displacement = radius of the circle

→7 cm = 0.07 m

and time = 5 seconds

thus,

v = 0.07/5 = 0.014 m/s

Hope it helps...

Answer 2

Answer:

22m

Explanation:

distance = pie*radius

d= 22/7 * 7

d= 22m
