A car travels with a uniform velocity of...

A car travels with a uniform velocity of 25 m `s^(-1)` for 5 s. The brakes are then applied and the car is uniformly retarded and comes to rest in further 10 s. Find : (i) the distance which the car travels before the brakes are applied, (ii) the retardation,and (iii) the distance travelled by the car after applying the brakes.

Text Solution

Verified by Experts

Initial velocity `u=25 "ms"^(-1)`
Before the brakes are applied ,
s=distance travelled
Distance = Speed x time
Or, s=25 x 5
`therefore` s=distance travelled before the brake is applied = 125 m

A car travels with a uniform velocity of 20 m s^(-1) for 5 s. The brakes are then applied and the car is uniformly retarded. It comes to rest in further 8 s. Draw a graph of velocity against time. Use this graph to find : (i) the distance travelled in first 5 s, (ii) the distance travelled after the brakes are applied, (iii) total distance travelled, and (iv) acceleration during the first 5 s and last 8 s.

A train starts from rest and accelerates uniformly at a rate of 2 m s^(-2) for 10 s. It then maintains a constant speed for 200 s. The brakes are then applied and the train is uniformly retarded and comes to rest in 50 s. Find : (i) the maximum velocity reached, (ii) the retardation in the last 50 S, (iii) the total distance travelled, and (iv) the average velocity of the train.

A train starts from rest and accelerates uniformly at 100 m "minute"^(-2) for 10 minutes. Find the velocity acquired by the train. It then maintains a constant velocity for 20 minutes.
