A large crate of mass 1500 kg starts sliding from

Chapter 4, Problem 4.89

(choose chapter or problem)

A large crate of mass 1500 kg starts sliding from restalong a frictionless ramp, whose length is t and whose inclinationwith the horizontal is 0. (a) Determine as a functionof 6: (i) the acceleration a of the crate as it goes downhill,(ii) the time t to reach the bottom of the incline, (iii) thefinal velocity v of the crate when it reaches the bottom ofthe ramp, and (iv) the normal force FN on the crate, (b) Nowassume i = 100 m. Use a spreadsheet to calculate andgraph a, t, v, and FN as functions of 6 from 0 = 0 to 90 in1 steps. Are your results consistent with the known resultfor the limiting cases 0 = 0 and 6 = 90?
