1. The problem statement, all variables and given/known data
A solid cylinder with a mass of 1.12 kg and a radius of 0.017 m starts from rest at a height
of 3.40 m and rolls down a 77.7◦ slope. What is the translational speed of the cylin-
der when it leaves the incline? The acceleration of gravity is 9.81 m/s2 . Answer in units
of m/s.
2. Relevant equations
I have angular speed which is
v=r$$\omega$$

we know r (.017m). But I'm having trouble finding the others.
Any help would be great. Thanks.
