Reference no: EM13332539

A 1.5kg block intially at rest at the top of a 3m incline with a slope of 30degrees begins to slide down the incline. The upper half of the incline is frictionless, while the lower half is rough, with a coefficient of kinetic friction equals 0.3.

A. How fast is the block moving midway along the inlcine, before entering the rough section? Answer given is 3.84m/s.

B. How fast is the block moving at the bottom of the incline?Answer given is 4.67m/s.
