(a) the final velocity

(b) the distance travelled.

Lakhmir Singh & Manjit Kaur - PhysicsObtain a relation for the distance travelled by an object moving with a uniform acceleration in the interval between 4^{th} and 5^{th} second.

A car accelerates from 6 ms^{–1} to 16 ms^{–1} in 10 sec. Calculate (a) the acceleration and (b) the distance covered by the car in that time.

A bus increases its speed from 36 km/h to 72 km/h in 10 seconds. Its acceleration is :

Lakhmir Singh & Manjit Kaur - PhysicsA bus is moving with a speed 72 km/h can be stopped by brakes after at least 10 m. What will be the minimum stopping distance, if the same bus is moving at a speed of 144 km/h?
