Centripetal acceleration is given by `a = k^2 r t^2`. Find power delivered by the force.

The centripetal acceleration is given by

A particle of mass "m" is moving along a circular path of radius 'r' such that "l centripetal acceleration a_(c)=k^(2)rt^(2) .power delivered to the particles is: 1) mk^(2)r^(2)t 2) 2mk^(2)r^(2)t 3) 1/2(mk^(2)r^(2)t 4) Zero

A particle of mass M is moving in a circle of fixedradius R in such a way that its centripetal accelerationn at time t is given by n^2Rt^2 where n is a constant. The power delivered to the particle by the force acting on it, it :

A block of mass 3 kg is pulled up on a smooth incline of angle 37^@ with the horizontal. If the block moves with an acceleration 2(m)//(s^2) , find the power delivered by the pulling force at time 5 s after the motion starts. What is the average power delivered during the 5.0 s after the motion starts?

A particle moves on a circle of radius r with centripetal acceleration as function of time as a_c = k^2 r t^2 , where k is a positive constant. Find the following quantities as function of time at an instant : (a) The speed of the particle (b) The tangential acceleration of the particle ( c) The resultant acceleration, and (d) Angle made by the resultant with tangential direction.

A particle of mass m is moving in a circular path of constant radius r such that its centripetal acceleration ac is varying with time t as a_c = k^2rt^2 , where k is a constant. Calculate the power delivered to the particle by the force acting on it.
