Brakes are applied to a train moving with a velocity of 20 m/s. If the train comes to a halt after 10 seconds, calculate the acceleration of the train. Find the distance covered by the train after the brakes are applied.

A motorboat starts from rest and moves with uniform acceleration, if it attains the velocity of 15 m//s in 5s, calculate the acceleration and the distance travelled in that time.

Answer the following questions: A train is moving with a uniform velocity of 60km/hout for 5 hours. The velocity-time graph for this uniform motion show in figure. Is there a relation between the distance covered by the train between 2 and 4 hours and the area of a particular quadrangle in the graph? What is the acceleration of the train?

A particle is moving with velocity 5 m/s towards east and its velocity changes to 5 m/s north in 10 s. Find the acceleration.

A body starting with an initial velocity of 5 m//s , moves with a uniform acceleration of 2 m//s^(2) . After some time it attains a velocity of 13 m//s . Find the distance covered by the body during this period.

The initial velocity of a body is 10 m//s . If it is moving with a uniform acceleration of 3 m//s^(2) in the direction of motion, calculate the distance covered by the body in 20 seconds.

A body moves with a velocity of 10 m/s for 10 s and then with a velocity of 20 m/s in the same direction for 40 s. Find its average velocity.

When sound is produced in an aeroplane moving with a velocity of 250 m//s horizontally its echo is heard after 12 seconds. If velocity of sound in air is 300 m s^(-1) , the elevation of aircraft is

A local train, travelling at 72 km/hr is brought to rest in 10 seconds by applying the brake. How much is the acceleration produced in this case? Also how much is distance (s) covered by the train before coming to rest?

Answer the following questions: A train is moving with a uniform velocity of 60km/hour for 5 hours. The velocity-time graph for this uniform motion show in figure. i. With the help of the graph, how will you determine the distance covered by the train between 2 and 4 hours

A train is moving at 20 m//s on a railway track of radius of curvature 1600 m. If the distance between two tracks is1.8 m, then the elevation of the outer track above the inner track will be
