Question

A car starts from rest and maintains an acceleration of 4.5 (m/s) for 5 s. How To
end of the 5 s?​

Answer 1

Correct Questions :-

A car starts from rest and maintains an acceleration of 4.5 m/s² for 5 sec , How to find out the velocity at the end of 5 sec ?

Or the distance travelled at the end of 5 sec ?

Solution :-

As given

• Acceleration = 4.5 m/s²

• Intial Velocity = 0

• Time = 5 sec

So if it's velocity

v = u + at

→ v = 0 + 4.5(5)

→ v = 22.5 m/s

So if it's distance

S = ut + 1/2 at²

→ S = 0(5) + 1/2 × 4.5 × 5²

→ S = 0 + 1/2 × 4.5 × 25

→ S = 1/2 × 112.5

→ S = 56.25 m
