A car travelling with a speed of 20 km/hr comes into rest in 0.5 hour.

1.	A car travelling with a speed of 20 km/hr comes into rest in 0.5 hour. What will be the value of its acceleration in metre per second square
Answer» V = 0 km/hr U = 20 km/hr t = 0.5 hr Hence, Acceleration, a = (v-u) / t a = (0-20) /0.5 a = - 20/0.5 a = - 200/5 a = -40km/ h

A car travelling with a speed of 20 km/hr comes into rest in 0.5 hour. What will be the value of its acceleration in metre per second square

Answer»

V = 0 km/hr

U = 20 km/hr

t = 0.5 hr

Hence,

Acceleration, a = (v-u) / t

a = (0-20) /0.5

a = - 20/0.5

a = - 200/5

a = -40km/ h
