Answer with Explanation:
We are given that
Mass of rider=m=77 kg
Mass of bike =m'=7.3 kg
Initial velocity,u=9.3 m/s
Final velocity,v=6 m/s
A.Change in velocity=v-u=6-9.3=-3.3 m/s
Total mass,M=m+m'=77+7.3=84.3 kg
Change in momentum=
B.Impulse=Ft=Change in momentum=-278.19kg m/s
C.Time,t=13.2 s
Using the formula
F=
D.
