Question

A racing car start from rest and accelerates with a uniform acceleration of 4metre per second square. Calaclute the distance travelled by the car in 15 sec​

Answer 1

Correct Question:

A racing car has a uniform acceleration of 4m/s². What distance will it covering 15 seconds after the start?

Answer:

Uniform acceleration (a) = 4 m/s-²

Initial velocity (u)= 0 m/s

Time (t)= 15 sec.

Using second equation of motion:

$\tt{s = ut \times \frac{1}{2}at ^{2} }$

$\tt{s = 0 \times 15 \times \frac{1}{2} \times 4\times 15 ^{2} }$

$\tt{s = 450 \: ms { - }^{2} }$

Answer 2

Answer:

this is the answer
