Homework Statement
All answers shuold be in terms of m,g, θ ,μk and μs
1.Write the equation used to calculate the force required to move a block of mass m across a floor with a constant velocity. [SOLVED]
2.Write the equation to calculate the tension in a rope holding a block of mass m motionless on a ramp. [SOLVED]
3.Write the equation used to calculate the tension in a rope that is dragging a block of mass m up a ramp with constant acceleration.[SOLVED]
4Write the equation used to calculate net force on a block of mass m that is accelerating down a ramp.
Homework Equations
Well, you are supposed to write the equations :P
The Attempt at a Solution
1.Okay for number 1, since the velocity is constant the acceleration is 0. In other words F - f = 0 where f is the friction force. So the force will be F = f. and since everything has to be in the terms as the provided instructions tell us, my final answer will be F = μsmg.
2. Here is where I stopped and got a little confused. I think that the force is just mgsin(θ). In other words I think that my final answer is F = mgsin(θ).
3. I am stuck here :P.Note: As we progress, I will put [SOLVED] around the solved questions.
Thanks for any help!
