Question

Car is moving along a straight line at a speed of 54km/hr stop in 5sec after the brakes are applied
Find acceleration assuming it to be constant
Plot the graph of speed versus time
Using the graph find the distance covered by the car after the brakes are applied

Answer 1

Hello Mate!

Please refer to attatchment.

First convert 54 km/h into m/s

Then, equations of motion used is v = u + at

Then take out distance covered by finding out area of triangle form.

The graph obtained shows a uniform retardation.

Have great future ahead!
