Question

If the speed of an object is doubled and time taken of an object is reduced to half, what about acceleration

Answer 1

Answer:

If speed of an object revolving in a circular path is doubled and regular speed is reduced to half then centripetal acceleration is as below,

a=v

2

r

a

′

=(2v)

2

/2r

=4v

2

/2r

=2a.

∴ the centripetal acceleration doubles.

Hence'
