Let's assume that the car, of mass 1550 kg, can reach a speed of 26.8 m/s in 7.1 s. What is the average power needed to accomplish this? (Given : 1 hp = 746 Watt)

A car of mass 1000 kg runs with a velocity of 10 m/s. what is the momentum of this car?

What is the kinetic energy of a body of mass 1 kg moving with a speed of 2 m/s ?

A man walks for 1 minute at a speed of 1m/s and then runs for 2 minute at 3m/s. What is the average speed of the man?

A man walks for 1 minute at a speed of 1m/s and then runs for 2 minute at 3m/s. What is the average speed of the man?

A body of mass 1 kg is acclerated uniformly from rest to a speed of 5 m/s in 4 sec. What is the instantaneous power delivered to the body at time t? (Assume t lt 4 sec.)
