Question

a stone of mass 50gm is being rotated in the circle of radius 50cm with a uniform speed of 2m/s . what is the acceleration of stone?

Answer 1

hello friend..!!

• According to the question , we should calculate the acceleration of the stone.

given :

m = 50gm = 50 /1000 kg

r = 50 cm = 50 / 100 m

v = 2 m/s

since the stone is moving in a circular motion ,

a = mv ^2 / r

implies,

a = 50 x 2 x 2 x 100/ 1000 x 50

therefore,

a = 0.4 m/s^2

therefore the acceleration of the
stone is 0.4m/s^2
