Gravity, speed, and energy?, Physics

Assignment Help:
A solid cylinder of radius 12.1cm and mass 20.2kg starts from rest and rolls without slipping a distance of 6.14m down the house roof that is inclined at 25.3° relative to the horizontal.

a) What is in Joules, the initial gravitational potential energy of the cylinder relative to the bottom of the roof?

b) What is in rad/s the angular speed of the cylinder about its center when at the bottom of the roof?


c) What is in J its rotational kinetic energy then?


d) What is in J its linear kinetic energy then?


Use 10.0 N/kg for g.
