A train moves with a uniform velocity of 36 km/h for 10s. Find the distance traveled by it.
A train starts from rest. It moves through 1 km in 100s with uniform acceleration. What will be its speed at the end of 100s?
A car has a velocity of 10 m/s. It accelerates at 0.2 m/s² for half minute. Find the distance traveled during this and the final velocity of the car.
A tennis ball is hit vertically upward with a velocity of 30 m/s. It takes 3 s to reach the highest point. Calculate the maximum height reached by the ball. How long will it take to return to ground?
A car moves with uniform velocity 40 m/s for 5 s. It comes to rest in the next 10 s with uniform deceleration. Find the total distance traveled by the car.
A train starts from rest with an acceleration of 0.5 m/s². Find its speed in km/h when it has moved through 100 m.
A train starting from rest accelerates uniformly and attains a velocity 48 km/h in 2 minutes. It travels at this speed for 5 minutes. Finally, it moves with uniform retardation and is stopped after 3 minutes. Find the total distance traveled by the train.
A cricket ball is hit vertically upwards and returns to ground 6 s later. Calculate (i) Maximum height reached by the ball. (ii) Initial velocity of the ball.
When brakes are applied, the speed of a train decreases from 96 kmb to 48 kmh in 800 us. How much further will the train move before coming to rest? (Assuming the retardation to be constant)

2.10 In the above problem, find the time taken by the train to stop after the application of the brakes.
A cyclist is moving at a constant speed of 20 km/h. How much time will it take for the cyclist to cover a distance of 5 km?
A train travels a distance of 120 km at a speed of 60 km/h, then continues for another 80 km at 80 km/h. What is the average speed of the train over the entire journey?
