(Answered) Starting from rest an10 kg block slides 119 m down a

Academics

Starting from rest, a(n)10 kg block slides 11.9 m down a frictionless ramp (inclined at 30? from the floor) to the bottom. The block then slides an additional 21.1 m along the floor before coming to stop.

The acceleration of gravity is 9.8 m/s2. Find the speed of the block at the bottom of the ramp.

Answer in units of m/s. Find the coefficient of kinetic friction between block and floor.
