A train accelerating uniormly from rest attains a maximum speed of `40ms^(-1)` in `20s`. It travels at this speed for `20s` and is brought to rest with uniform retardation i further `40s`. What is the average velocity during this period?

If a car accelerates uniformly from rest and attains a speed of 40 ms^-1 in 10s, it covers a distance of

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.

Starting from rest, a car movies with uniform acceleration and attains a velocity of 72 km hr^-1 in 20 s. It then moves with uniform speed for 25 s and is brought to rest in 10 s under uniform retardation. Find the total distance travelled using velocity-time graph.

A train starting from rest, and moving with uniform acceleration alpha , acquires a speed v. Then its comes to a stop with uniform retardation beta . Then the average velocity of the train is

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 retardation

A motor car starts from rest and accelerates uniformly for 10 s to a velocity of 20 ms^(-1) . It then runs at a constant speed and is finally brought to rest in 40 m with a constant acceleration. Total distance covered is 640 m. Find the value of acceleration, retardation and total tie taken.

A truck starts from rest and accelerates uniformly to a velocity of 40m/s in 10s, it then runs with this uniform velocity and is finally brought to rest in 50m by a uniform deceleration. If the total run of the truck is 500m, find its acceleration and total time of journey.
