Question

statement
4. A car travels at a speed of 60km/hr due north and the other car at a speed of 60km/hr due east
are the velocities are equal.
nood of Ankm/hr apply the brakes giving deceleration of 6m/sec2 to his​

Answer 1

this is the answer of your question

Answer 2

Answer:

FIRST CONVERT THE SPEED OF car IS m/s.

speed of car=

when brakes were applied final velocity would become zero.

apply third equation of motion:-

0^2 - (250/18)^2 = 2*a*6

a = -16.075 m/s^2

now when speed is 250\9 m/s

s= 0^2 - (250/9)^2 \ 2*16.075

now you do the calculation
