The giant monster NADIAZILLA is dangling Doug by his belt. Doug weighs 650 N. If NADIAZILLA accelerates Doug upwards at 3.5 m/s^2 before flinging him into the Ottawa River, what is the tension in Doug's belt?

Question

anonymous · Answer

The tension in Doug's belt will be equal to the applied force (the force that the moster exerts on Doug).

F(weight) = 650 N
a = 3.5 m/s^2
g = 9.81 m/s^2

F(weight) = mg
m = 650/9.81 = 66.26 kg

F(net) = ma
F(net) = (66.26)(3.5) = 232 N

F(net) = F(applied) - F(weight)
F(applied) = F(net) + F(weight)

F(applied) = 232 + 650 = 882 N
