Problem: A rolling pin rolls down a 2m incline that forms a 60 degree angle with the ground. The rolling pin's moment if inertia is 25 kgM2 its mass is 5 kg and its radius is 15 cm.
Part A: What is the final velocity of the rolling pin if there is no friction?
I need help to find the final velocity of the rolling pin if there is no friction.
In a typical fender bender, a 1500 kilogram car traveling at 48 kilometer per hour collides in elastically with a 1200 kilogram car traveling at 32 kilometer per hour in the similar direction. Determine how much of the initial kinetic energy of th..
Demonstrates how the forces can vary in problems of this type. A hiker, who weighs 857 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 4420 N, and rests on two concrete supports, one on each end.
