Question

A racing car has uniform acceleration of 4ms. What distance will it cover in 10s after start?

Answer 1

Answer:

40ms per second

Explanation:

after start the the car covers distance of 40m/s

Answer 2

The distance covered by the car is 200 meters.

Explanation:

It is given that,

Acceleration of the racing car, $a=4\ m/s^2$

We need to find the distance covered by the car in 10 seconds after start. It can be calculated using second equation of motion.

$s=ut+\dfrac{1}{2}at^2$

Initially, the car is at rest, u = 0

$s=\dfrac{1}{2}at^2$

$s=\dfrac{1}{2}\times 4\times (10)^2$

s = 200 meters

So, the distance covered by the car is 200 meters. Hence, this is the required solution.
