Question

Q.1. A car moving along a straight line at a speed of 54km/hr stop in 58
after the brakes are applied. (a) Find the acceleration, assuming it to be
constant (b) Plot the graph of speed versus time (c) Using the graph. Find
the distance covered by the ear after the brakes are applied?
​

Answer 1

Answer:

v=u+at (first equation of motion)

Substituting the values

0=15+a×5

0=15+5a

−15=5a

−

5

15

=a

−3=a

Therefore acceleration is −3 m/s
