A vehicle starts moving along a straight line path from rest. In first t seconds it moves with an acceleration of 2 m/s² and then in next 10 seconds it moves with an acceleration of 5 m/s². The total distance travelled by the vehicle is 550 m. The value of time t is

Starting from rest a vehicle accelerates at the rate of 2 m/s² towards east for 10s. It then stops suddenly. It then accelerates again at a rate of 4√2 m/s² for next 10 s towards south and then again…

The area under the velocity-time graph for a particle moving in a straight line with uniform acceleration gives

A car has an initial velocity of 12 m/s and is brought to rest over a distance of 45 m. The acceleration of the car is

A bus starting from a bus-stand and moving with uniform acceleration attains a speed of 20 km/h in 10 minutes. What is its acceleration?

A car moves along a straight road, covering a displacement x with a constant velocity V₁ and then another equal displacement x with a constant velocity V₂. What is the average velocity of the car for…
