Question

if a car is moving with a velocity of 100km per hour. and applied brake for 2 second then find age of a driver​

Answer 1

Answer:

Let us first analyse the question. The car is travelling at some speed. And it has to stop. What distance will it cover before it stops?

Firstly, it is travelling at a speed of 100 kilometers per hour. And the deceleration provided is given in meters per second. So, let us convert all the data into same terms.

that is, 100 kmph = 100*1000 meters per hour

Answer 2

i think u want to ask:

if a car is moving with a velocity of 100 km per hour and applied break for 2 second then find the acceleration of car .

$\huge\underline\mathfrak\red{ANSWER}$

u = 0 m/s (starting from rest)

v = 100 km/h

= 100000 m /s

t = 2 sec

accn = v-u/t

= 100000 -0/2

= 100000/2

= 50000 m/sec^2
