A car start from rest and acquire a velocity of 54 km/h in 2 sec. Find (i) the acceleration (ii) distance travelled by car assume motion of car is uniform?

A force of 5N changes the velocity of a body from 10ms^-1 to 20ms^-1 in 5 sec. How much force is required to bring about the same change in 2 sec.

To maintain a rotor at a uniform angular speed of 200 rad s~ 1, an engine needs to transmit a torque of 180 Nm. What is the power required by the engine? (Note: uniform angular velocity in the absence of friction implies zero torque. in practice, applied torque is needed to counter frictional torque). Assume that the engine is 100 % efficient.
