Here since the car stops it's final velocity will be zero.
Given initial velocity = 72km/hr
We need to change it into m/s
=
20m/s
So acceleration =
v = final velocity
u = initial velocity
t = time
So acceleration =
Negative sign means acceleration is in opposite direction of velocity.
So Distance travelled (s) =
90 metre
Hope it helps dear friend ☺️✌️✌️
