Question

the brakes and tires of a car can provide a maximum acceleration of about 6 metre per second square if a car is traveling at a hundred kilometre per hour what is the minimum distance in which it could stop​

Answer 1

Hii Dear,

◆ Answer -

Minimum stopping distance = 64.3 m

◆ Explaination -

# Given -

a = -6 m/s^2

v = 100 kmph = 27.78 m/s

# Solution -

Let s be the minimum distance at which the vehicle can be stopped.

According to Newton's 3rd law of motion -

v^2 = u^2 + 2as

0^2 = 27.78^2 + 2×(-6)×s

27.78^2 = 12s

s = 771.6 / 12

s = 64.3 m

Hence, minimum distance required for vehicle to stop is 64.3 m.

Thanks ...
