... 9. A 205 kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30o from the horizontal. The coefficient of kinetic friction between the log and ramp is 0.900 and the log has an acceleration of 0.800 m/s2 up the incline. Find the tension in ...

... 8. Near the end of its life, the sun will swell in radius to engulf Mercury, Venus, and the Earth. What will happen to its angular velocity and why? The angular velocity will fall. Angular momentum is conserved, and as the sun expands, its moment of inertia will increase. The angular velocity will f ...
