Question

a racing car has a uniform acceleration of 4 m/s square. what distance will it cover in 10 seconds after the start?​

Answer 1

Answer:

200m

Explanation:

s=ut+1/2at^2

u=0

s=1/2at^2

s=1/2×4×(10)^2

s=200

Answer 2

Answer:

200 m

Explanation:

Given :-

A racing car has a uniform acceleration of 4 m/s².

To find :-

What distance will it cover in 10 seconds after the start.

Solution :-

Using equation of motion,

s = ut + 1/2 at²

Where,

s - distance

u - initial velocity

a - acceleration due to gravity

t - time

Accordingly,

u - 0 m/s (since the car starts from rest)

a - 4 m/s²

t - 10 seconds

Substituting we get,

s = 0 × 10 + 1/2 × 4 × 10²

s = 200

∴ Distance that the car will cover in 10 seconds after the start is 200 m.
