Question

A vehicle is moving at 5ms-1.how long will it take to stop at a distance of 15m?

Answer 1

Answer:

So, the vehicle could continue travelling at 5 m/s until, after 3 seconds ... a car moving 72 km·h-1 on a straight road is fully pressed, the car can stop in 50 m. ... from the initial velocity, 5 m/s, to zero velocity at a distance of 15 m.

Explanation:

Answer 2

Answer:

${v}^{2} = {u}^{2} + 2as \\ 0 = 25 \: + 2a \times 15 \\ a = - \frac{5}{6} \\ v = u + at \\ 0 = 5 - \frac{5}{3} \times t \\ t = 3$

hope the answer will help you
