mg downward
30 N upward
net downward = m g - 30
g is not in Newtons but in m/s^2.
It is more like 9.81 m/s^2 on earth but ok, use 10 m/s^2
net downward = 5 kg ( 10 m/s^2) - 30
= 50 - 30
= 20 Newtons
the total force opposing motion of the box and the parachute at particular time during its fall is 30N.the combined mass of the box and parachute is 5kg
1. Caculate the resultant downward force and box and the parachute (g=10N)
