d=1/2*10s*20m/s+1/2*20s*20m/s=100m+200m=300m avg velocity=total distance/total time=300/30=10m/s

laws of motion
since the force applied gives the body kinetic energy from rest:fd=1/2mv^2 d=1/2at^2 250=1/2a(5)(5) a=20m/s^2 since body start from rest u=0:a=v/t 20=v/5 v=100m/s from the equation:f(250)=1/2*0.9*100^2 250F=4500 F=18N
