A 20 kg crate is allowed to slide down a 60-m long smooth inclined plane which is 30° with the horizontal. At the bottom of the inclined plane, the crate is allowed to slide horizontally with the ground where the coefficient of friction between the crate and the ground is 0.15. After 1 m, the crate would meet a coil with a spring constant of 1000 N/m. (Assume that the friction no longer acts as the crate hits the spring).Calculate...

The 190-lb carriage has an initial velocity of 10.3 ft/sec down
the incline at A, when a constant force of 65 lb is
applied to the hoisting cable as shown. Calculate the velocity of
the carriage when it reaches B. Show that in the absence
of friction this velocity is independent of whether the initial
velocity of the carriage at A was up or down the
incline.
