Question
A sphere of mass 2 kg is thrown down with a velocity of 5 m / s from a height of 10 m,
by a smooth surface track. Descending to ground level, you come across a 10 m long stretch of rustic surface trail. Just when leaving the rustic surface its speed is 11.14 m / s, determine: a) the coefficient of kinetic friction of the rustic surface, b) the speed with which it entered
in the section of rustic surface.
