Answer on Mechanics | Relativity Question for akhil madhu

Question #12828
a motor car slows down from 72km/h to 332km/h over a distance of 25m.if the breaks are applied with the same force.caculate:-

i) total time in which it comes to rest.

ii)distance travelled by it.
Expert's answer
i) total time in which it comes to rest.

Let's find the deceleration of a car. The deceleration time is

t = 0.025km / ((72km/h-32km/h)/2) = 0.00125h.

Deceleration of a car is

a = (72km/h-32km/h) / 0.00125h = 32000km/h².

So, it will come to rest in

T = 72km/h / 32000km/h² = 0.00225h.

ii)distance traveled by it.

L = 0.00225h * (72km/h/2) = 0.081km.
