Avg force is given by:
F = dP/dt
F = m*dV/dt
Given values are:
m = 0.620 kg
dt = 0.115 sec
dV = Vf - Vi = 2.20 - (-2.40) = 4.6 m/sec
So,
Favg = 0.620*4.6/0.115
Favg = 24.8 N

1.) A 72-kg woman holds a 9-kg package as she
stands within an elevator which briefly accelerates upward at a
rate of 0.27g. Determine the force R which the elevator
floor exerts on her feet and the lifting force L which she
exerts on the package during the acceleration interval. If the
elevator support cables suddenly and completely fail, what values
would R and L acquire?
2.) The quarter-circular hollow tube...
