A uniform solid cylindrical log begins rolling without slipping down a ramp that rises 15.0 ∘ above the horizontal. After it has rolled 4.50 m along the ramp, what is the magnitude of the linear acceleration of its center of mass?
First, find the vertical distance covered
Consider the incline
=================
When the log rolls, initial potential energy is converted to rotational kinetic energy and translational kintic energy
-----------
Moment of inertia of solid cylinder,
and angular velocity,
------------
=========
Given that the log starts from rest
so
Use formula to find acceleration
