A 126 kg crate is sitting at the top of a ramp, which is inclined at an angle of 19 degrees with respect to the horizontal. The crate is a height 0.71 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 ls = 0.23. How much time (in seconds) does it take for the crate to get to the base of the ramp?

The diagram below represents a system consisting of two masses: mi=14 kg and m2=40kg, one of them on an incline and the other one hanging. The pulley is massless and frictionless and the cords joining the masses are ideal. The angle of the incline is 0=35°. The coefficient of kinematic friction is Hk=0.22 and we know the system starts to move from rest. a) Find the system's velocity (magnitude and direction) after moving 25 m along the incline.
