Question

I will mark your answer as brainliest...... please answer it.... i need your help.... please.... and no spams please....
A car travels with uniform velocity of 20 m/s for 5s. The brakes are then in applied and the car is uniformly retarded. It comes to rest in further 8s. Draw a graph of velocity against time. Use this graph to find :
(a) The distance travelled in first 5s.
(b) The distance travelled after the brakes are applied.
(c) Total distance travelled.
(d) Acceleration during the first 5s and last 8s.

Answer 1

Hello there
So as you know that area under V-T graph gives you distance travelled...so after making graph simply calculate area to find the answers of first and second part...
For better understanding I'm attaching a picture of complete answer..
Hope it helps you...(if it does mark the answer as brainliest)

Thanks
