An automobile engine propels a 1000 kg car (A) along a levelled road at a spedd of 36 km//h. Find the power if the opposing frictional force is 100 Now, suppose after travelling a distance of 200 m, this car collides with another stationary car (B) of same mass and comes to rest. Let its engine also stop at the same time. Now car (B) starts moving on the same level road without getting its engine started. Find the speed of the car (B) just after the collision.

An automobile engine propels a 1000 kg car (A) along a levelled road at a speed of 36 km//h. Find the power if the opposing frictional force is 100 N Now, suppose after travelling a distance of 200 m, this car collides with another stationary car (B) of same mass and comes to rest. Let its engine also stop at the same time. Now car (B) starts moving on the same level road without getting its engine started. Find the speed of the car (B) just after the collision.

Car A of mass 1000 kg moves on a horizontal straight road with speed 36kmh^(-1) . If the force resisting the motion is 100 N, then find the power of the engine. Now, after covering 200 m distance, car A collides with a stationary car B of same mass and becomes stationary. As a result car B start moving on the horizontal road, then what would be the speed of car B just after the collision? (The engine of car B is off.)

An engine accelerate a car of mass 800 kg to a speod of 72 km//h . If the frictional force is 10 N per tonne, the power developed by the engine is:

A car moving along a straight road with a speed of 120 km/hr, is brought to rest by applying brakes. The car covers a distance of 100 m before it stops. Calculate (i) the average retardation of the car (ii) time taken by the car to come to rest.

A rail road car of mass M is at rest on frictionless rails when a man of mass m starts moving on the car towards the engine. If the car recoils with a speed v backward on the rails, with what velocity is the man aproaching the engine?
