PHYSICS

A car starts from rest and accelerates uniformly for 10 s to a velocity of 8 ms

−1

. It then runs at a constant velocity and is finally brought to rest in 64 m with constant retardation. The total distance covered by the car is 584 m. Find the value of acceleration, retardation, and total time is taken.
