Question

14. A racing car has uniform acceleration of 4 m/s2. How
much distance will it cover in 10 ​

Answer 1

Answer:

distance it will cover is

distance = acceleration times of second

$4 \times 10 = 40metre$

Answer 2

Answer:

Explanation:

Given, Acceleration a = 4 m/s^2

Time t = 10 s

Distance s =?

From 2nd equation motion s=ut+(1/2)at^2

Since we have to find the distance from start its initial velocity will be zero. ie u=0

Therefore s = 0+1/2×4×10²

= 2×100

= 200 m.

ie the racing car covers 200 m.
