Homework Statement
[/B]
My question is regarding Part B of this problem, I have solved it but I'm wondering if there is another way to solve it since it says dtheta/dt and one of the hints I found online suggested that I use the chain rule.
Homework Equations
Q = mc(deltaT)
Q/t = P
The Attempt at a Solution
For the first part, i just did theta/time to find angular velocity, then multiplied by radius to find the tangential velocity, then just multiplied by the force of 520N by pi/9, the tangential velocity to get 180 Watts.
For the second part I just divided the equation for Q by t to make deltaT/t=P/mc and got 0.064 C/s.
If there was a calculus way to solve this I'd appreciate some help. Thanks
