A car of mass 750 kg has an engine which produces a constant power of 40 kW. If the resistance to motion assumed constant is 800 N, Find the maximum speed at which the car can travel on the road. Also find the acceleration when it is travelling at 25m/s.

Without changing the angle of banking, if we want to increase the maximum safe speed, with which a car can travel on the curved road by 10% then what much we should increase the radius of curvature of the road from 20m.

The power engine which accelerates a car of mass 800 kg to a speed of 72 km/h from rest in 32s is

A car accelerates from rest at constant rate of 2m/s^2 for some time. Then it retards at constant rate of 4m/s^2 and comes to rest . If the total time for which it remains in motion is 3 seconds, what is the distance travelled ?

A car is moving on a circular track of diameter 72m with a speed of 6 m/s.It is accelerated at the rate of root3 m/s2.If the mass of the car is 1000 kg, Find the net force acting on the car.

A bus starts from rest with a constant acceleration of 5m/s^2 . At the same time , a car travelling with a constant velocity of 50m/s overtakes and passes the bus ,find (i)at what distance will the bus overtake the car ? (ii)How fast will the bus overtakes the car after distance S metres.
