Dr. L. has been asked by Caroline to clean some of his spare physics stuff out of the basement. To do so, he puts a ramp on the stairs which are at an angle of β above the horizontal. The crate of stuff has a mass C but Dali (mass D) jumps on top of it. Despite this, Dr. L. pulls on the rope and manages to make the crate and cat accelerate up the ramp together at a rate of A. As the crate accelerates, the cat remains stationary on top if it. Note that there is no friction between the ramp and the crate but there is some coefficient of friction between the cat and the crate and we call it μ. 5. Assuming Dali doesn’t slip, what is the tension in the rope? Answer in terms of g, μ, C, D, and β only.
