Since we know that the potential energy is equal to
mgh. And if we take storage rack's lower surface
is at zero potential,then
and
in question 2 ,whatever the velocity of Shawn have, its due to the
velocity of bike. Then the kinetic energy of Shawn can be
calculated as:-
For any doubt please comment and please give an up vote. Thank you
