A bus decreases its speed from 80 km//h to 60 km//h in 5 s . Find the acceleration of the bus.

A car accelerates uniformly from 18 kmh^(- 1) to 72 (kmh^- 1) in 5 s. The acceleration of the car is:

A bus decreases its speed from 72 km//h to 54 km//h in 10 s . Calculate the acceleration of the bus.

A car accelerates uniformly from 18kmh^(-1) " to " 72 kmh^(-1) in 10s. Calculate the acceleration of the car.

A race car accelerates on a straight road from rest to a speed of 180 kmh^(-1) in 25s. Assuming uniform acceleration of the car throughout, find the distance covered in this time.

One of the rectangular components of a velocity of 80 kmh^(-1) is 40 kmh^(-1) . Find the other component.

A man swins in a river with and against water at the rate of 15 kmh ^(-1) and 5 kmh^(-1) . Find the man's speed in still water and the speed of the river.
