The linear speed of a stone revolving 5 times in a circle of 4 cm radius in 2 minute is (in $cm s^{-1}$)
A particle of mass \(m\) is moving in a circular path of constant radius \(r\) such that its centripetal acceleration \(a_{c}\) is varying with time \(t\) as \(a_{c} = k^{2}rt^{2}\), where \(k\) is a constant. The power delivered to the particle by the forces acting on it is:
