➡A driver of a car traveling at 52km/h applies brakes and accelerates uniformly in the opposite direction . The car stops in 5s. Calculate the distance the car after the brakes were applied.

Answer⤵

➡36. 1m

Solution⤵

➡ Initial speed of the car

u=52 km/h =52× 5/18 =14.44 m/s

➡The car stops in 5 seconds i.e v=0 at t=5

➡Distance covered by car ➡1/2×14.44×5=36.1 m
