Q1. Starting from rest, a(n)13 kg block slides13.3 m down a frictionless ramp (inclined at 30? from the ?oor) to the bottom. The block then slides an additional 26.3 m along the ?oor before coming to stop.
The acceleration of gravity is 9.8 m/s.
Find speed of the block at the bottom of the ramp.
Answer in units of m/s
