The electric motor of a model train accelrates the train from rest to `0.620ms^-1` in `21.0ms`. The total mass of the train is `875g`. Find the average power delivered to the train during the acceleration.

A man travels a distance of 196 km by train and returns in a car which travels at a speed of 21 km/hours more than the train if the total journey takes 11 hour. Find the average speed of the train and the car respectively.

A train starting from rest attains a velocity of 72 km/h in 5 minutes. Assuming that the acceleration is uniform Find the distance travelled by the train for attaining this velocity.

A train starts from rest and moves with a constant accelerationof 2.0 m/s^2 for half a minute. The brakes are then applied and the train comes to rest in one minute. Find a. the total distance moved by the train, b. the maximum speed attained by the train and c. the position(s) of the train at half the maximum speed.

A train starts from rest with constant acceleration a=1 m//s^(2) A passenger at a distance S from the train runs at this maximum velocity of 10 m//s to catch the train at the same moment at which the train starts. Find the speed of the train when the passenger catches it for the critical distance:

Two trains P and Q are moving along parllel tracks same uniform speed of 20 m s^(-1) . The driver of train P decides to overtake train Q and accelerate his frain by 1 ms^(-2) , After 50 s , train P crosses the engine of train Q . Find out what was the distance between the two trains initially. provided the length each is 400 m .

Give the magnitude and direction of the force acting on a stone of mass 0.1 kg (a) just after it is dropped from the window of a stationary train (b) just after it is dropped from the window of a train running at a constant velocity of 36 km//hr (c) just after it is dropped from the window of a train accelerating with 1 ms^(-2) (d) lying on the floor of a train which is accelerating with 1 ms^(-2) the stone being at rest relative to the train . Neglect the resistance of air throughout .
