Question

A car of mass 1500 kg starting from rest can reach a speedof 20m/s within 10 sec. calculate the accelerating force of the car engine.

it is physics not mathematics.

Answer 1

given mass =1500kg

intial velocity(u)=0 m/s

final velocity(v)=20m/s

time(s)=10 sec

accelerating force of the car engine=final velocity-intial velocity/time=20-0/10=20/10=2m/s^2
