Homework Statement
A solid cylinder of mass 0.600kg is released from rest and allowed to roll down a board that has an incline of 30degrees to the horizontal floor. If the solid cylinder is released 0.60m above the floor, what is the cylinder's linear speed when it reaches the lowest end of...
Given a plot of Torque vs Angular acceleration, would it be valid to say that the slope of that line would be the Rotational inertia and the Y intercept to be equal to the force of friction?
I think there could be an argument for the Y intercept being the force or TORQUE due to friction. what...
Okay that makes sense. thank you.
So if i were to calculate work done by friction, but this time I'm given distance and delta K, would I use Wncf=fd where f=(deltaK)/d or work energy theorem?
Homework Statement
You have a level track. You push a cart with mass = 1.12[kg].
You measure the initial velocity to be 0.57[m s-1].
2 seconds later, you measure the velocity to be 0.427[m s-1].
