A body starting from rest acclerates uniformly along a st. line , at the rate of `10 ms^(-2)` for 5 s. It moves for `2 s` with uniform velocoty of `50 ms^(-1)`. The it retards uniformly and comes to rest in 3 s`. Draw velocity-time graph of the and find the total distance travelled by body.

A body starts from rest and accelerates uniformly at 5m//s^(2) for 7 seconds, along a straight line, it then starts decelerating at a rate of 2m//s^(2) for the next 5 seconds, moves uniformly with a velocity of 25m/s for the next 2 seconds and then retards again and comes to rest in another 3 seconds. (i) Plot the velocity versus time graph for the body. (ii) Calculate the total distance travelled by the body with the help of the graph.

Starting from rest a car accelerates unifromly with 3 ms^(-2) for 5 s and then moves with uniform velocity. Drwa the distance-time graph of the motion of the car upto t = 7s.

A body starting from rest accelerates uniformly at the rate of 10cms^(-2) and retaeds uniformly at the rate of 20cms^(-2) . Find the least time in which it can complete the journey of 5km if the maximum velocity attained by the body is 72kmh^(-1) .

A Bullet Train in Japan starting from rest accelerates uniformly at 0.5m s^(-2) for 2 minutes. It then maintains uniform speed for 20 minutes and then retards uniformly at the rate of 0.25 m s^(-1) and comes to rest. Calculate the average speed of the train

A motor car, starting from rest, moves with uniform acceleration and attains a velocity of 8 ms^(-1) in 8 s. It then moves with uniform velocity and finally brought to rest in 32 m under unifrom retardation. The total distance covered by the car is 464 m. Find the total time taken.

An automobile starts from rest and accelerates unifomly for 30 second to a speed of 72 km h^(-1) . It then moves with a uniform veocit and it is finally brought to rest in 50 m with a constant retardation. If the total distance travelled is 950 m , find the accleration, the retaradation and total time taken.

Starting from rest a car moves with uniform acceleration and attains a velocity of 72 kmh^(-1) in 15 s. It then moves with uniform speed for 20s and is then brought to rest in 10 s undere uniform retardation. Find total distance travelled using velocity - time graph.
