A small electric car has a maximum constant acceleration of `1m//s^(2)`, a maximum constant deceleration of `2m//s^(2)` and a maximum speed of `20m//s`. The amount of minimum time it would take to drive this car `1km` starting from rest is `(13n)` second. Find value of `n`

A car is to be hoisted by elevator to the fourth floor of a parking garage, which is 14 m above the ground. If the elevator can have maximum acceleration of 0.2 m//s^2 and maximum deceleration of 0.1 m//s^2 and can reach a maximum speed of 2.5 m//s, determine the shortest time to make the lift, starting from rest and ending at rest.

Two cars a and B starts motion with a velocity of 10 m//s and 20 m//s respectively. Car a moves with a constant acceleration of 2.5 m//s^(2) and car B have constant acceleration of 0.5 m//s^(2) as shown in figure. Find when car A will over take car B. Dimension of car is negligible as compare to distance. Find the time after which car A over takes car B.

A car accelerates by 50 m//s^(2). It would, attain a speed of 100 km per hour from rest in

Engine of a car can produce a maximum acceleration 2 m//s^(2) and its brakes can produce a maximum retardation 3 m//s^(2) . Minimum time in which the car can travel a distance 6 km is:

A car starts accelerating with an acceleration of (1)/(3)m//s^(2) when its speed was 18 km//h . If the desplacement of car in n^(th) minute after it starts accelerating is 4.8km then n is :
