Question

bus running velocity 72km/h .on seeing a boy on the road 65m ahead, driver jamed on the break and bus stop ed with uniform retardation 5m/s2 .calculate distance travelled by the bus ​

Answer 1

A car running with a velocity = 72km/h

on a level road is stoped after travelling a distance of = 30m

after disengaging its engine =(g = 10m^2)

The coefficient of friction between the road and the tyres is = 0.67

USE FORMULA :-

v^2- u^2= 2as
