CBSE Class 9 Answered

a body covers a semicircle a radius 7 cm in 5 sec. find its velocity
Asked by | 19 Sep, 2013, 12:57: PM
answered-by-expert Expert Answer

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
