A train is travelling at a speed of 90 km `h^(-1)`. Brakes are applied so as to produce a uniform acceleration of – 0.5 m `s^(-2)`. Find how far the train will go before it is brought to rest.

A car is travelling at a speed of 90 km/h. Brakes are applied so as to produce a uniform acceleration of – 0.5 m/s2. Find how far the car will go before it is brought to rest?

A train is moving at a velocity of 120 km/h. Brakes were applied and an uniform retardation of 0.5 m//s^2 was produced. What distance will the train move before coming to a half?

A car is moving at a velocity 72 km/h. Brakes were applied. After moving a distance 200 m the car attains velocity 36 km/h.What distance will the train move before coming to rest.

A car is moving at a velocity 72 km/h. Brakes were applied. After moving a distance 200 m the car attains velocity 36 km/h. Find (i) acceleration of the car

A man of mass 70 kg stands on a weighing scale in a lift which is moving (a) upwards with a uniform speed of 10 m s^1 (b) downwards with a uniform acceleration of 5 m s^2, upwards with a uniform acceleration of 5 m s-^1z. What would be the readings on the scale in each case? What would be the reading if the lift mechanism failed and it hurtled down freely under gravity?

An object dropped from a cliff falls with a constant acceleration of 10 m/s2. Find its speed 5 s after it was dropped.

A flywheel of mass 25kg has a radius of 0.2 m. What force should be applied to the rim so that it acquires an angular acceleration of 5 rads^(-2) ?

Two persons manage to push a motorcar of mass 1200 kg at a uniform velocity along a level road, the same motorcar can be pushed by three persons to produce an acceleration of 0.2 m s^-2 . With what force does each person push the motorcar? (Assume that all persons push the motorcar with the same muscular effort.)

A motor car starting from rest travelled for 10 seconds with an uniform. acceleration of 5 m //s ^2 . What is the final velocity? Find the distance covered by the car.

Onna two-lane road, car A is travelling with a speed of 36 km h_1. Two care B and C approach car A in opposite directions with a speed of 54'km h_1 each. vAt a certain instant, when the distance AB is equal to AC, both being 1 km,* B’ decides to overtake A before C does. What minimum acceleration of car B is required to avoid an accident?
