Answer 1

Answer:

32m

Step-by-step explanation:

At a car travelling at a speed of 30km/h is brought to rest in a distance of 8m by applying brakes if the same car is moving at a speed of 60km/h then that it can be brought to rest with same brakes in:

$\frac{1}{2}mv$² = Fs

on the doubling, the speed and the required distance will become 4 times that is s=4×8=32m
