Question

how long would it take a car that starts from rest and accelerates uniformly in a straight line at 5 m/s^2 to cover a distance of 400 m?

Answer 1

Answer:

Initial velocity =>u = 0 m/s

Distance covered => S =400 m

Acceleration => a =5 m/s^2

$s = ut + \frac{1}{2} a {t}^{2} = >$

$400 = 0(t) + \frac{1}{2}(5) {t }^{2} = >$

$160 = t ^{2} = > t = 4 \sqrt{10} = 4 \times 3.16 \: s$

Time taken is 12.64 seconds. HOPE it helps you. Mark me as Brainliest if you think I am worth of it.
