A lift ascends with constant acceleration `a=1ms^(-2)`, then with constant velocity and finally, it stops under constant retardation `a=1ms^(-2)`. If total distance ascended by the lift is 7 m, in a total time of the journey is 8 s. Find the time (in second) for which lift moves with constant velocity.

A lift ascends with a constant acceleration of 4 m s^(-2) then with a constant velocity v and finally stops under a constant retardation of 4 m s^(-2) . If the total height ascended be 20 m and the total time taken is 6 s then the time during which the lift was movitng with a vclocity nu is

A left storing from rest assends with constants acceleration 'a', then with a constant velcoity and finally stops under a constant retardation 'a'. If the total distance assended is 'x' and the total time taken is 't',show that the time during which the left is assending with constant vlocity is sqrt(t^(2)-(4x)/a

A train starting from rest travels the first part of its journey with constant acceleration a, secondpart with constant velocity v nd third part with constant retardation a, being brought to rest.the average speed for the whole journey is7v8. The train travels with constant velocity for...of the total time -

A car starts form rest and accelerates uniformly for 10 s to a velocity of 8 ms ^(-1) . It then runs at a constant velocity an dis finally brought to rest in 64 m with a constant retardation. The totla distance covered by the car is 584 m Find the value of acceleration, retardation, and totl time taken.
