Answer:
5.160384 kg*m²/s
Explanation:
The vector angular momentum P can be found using the following expression:
P = I * w
I refers to the inertia, that for a sphere is found using the expression:
I = * m * r² = * 15.5kg * (0.510m)² = 1.61262 kg*m².
The angular velocity w is given by the problem, and has a value of 3.2 rad/s.
Replacing the data we get:
P = 1.61262 kg*m² * 3.2 rad/s = 5.160384 kg*m²/s
Claudia's mass is 51 kg, therefore her weight is
W = (51 kg)*(9.8 m/s) = 499.8 N
The bungee cord extends by x = 5m due to the weight.
By definition the spring constant for the bungee cord is
k = W/x = (499.8 N)/(5 m) = 99.96 N/m
Answer: The spring constant is 100 N/m (nearest tenth)
