Question

a car is speeding at 108Km/hr it has to stop at a distance of 10metres .Find the deceleration required .Also draw its v-t graph till it comes to at rest.​

Answer 1

first convert velocity into m/s by
180×3600/1000
then put in this formula
velocity/2×10=deaccleration
because v=u+2as u=0 because it is in motion
