A 121 kg crate is sitting at the top of a ramp, which is inclined at an angle of 18 degrees with respect to the horizontal. The crate is a height 0.51 m from the ground, measured vertically from the ground to the crate. Someone gives the crate a quick shove to get it moving, after which it slides down the ramp without any further assistance. The coefficient of kinetic friction between the crate and the ramp is Hs = 0.23. How much time (in seconds) does it take for the crate to get to the %3D base of the ramp?
