Question

What is the magnitude of the total force on a driver by the racing car he operates, as it accelerates horizontally along a straight line from rest to $60m/s$ in $8.0s$ (mass of the driver $=80kg$)

Answer 1

$u=0m/s,v=60m/s,m=80kg,t=8s$

$a=\frac{60-0}{8}=7.5m/s^2$

$F=ma$

$⟹F=7.5\times 80=600N$
