Question

A sports car picks up from rest and gains velocity of 180 km/h in 100 metre. Calculate its

acceleration​

Answer 1

Explanation:

Given that,

Time t=10sec

Velocity v=12km/h=

18

12×5

m/s

Now, the acceleration is

Using of equation of motion

v=u+at

12×

18

5

=0+a×10

a=

10×18

12×5

a=

3

1

m/s

2

Hence, the acceleration is
