Two cylinders of identical mass but with different radii roll down a ramp. in your initial post to the discussion, respond to the following: which cylinder gets to the bottom first? which cylinder has more total kinetic energy? why? now, using the concept of moment of inertia, explain why two objects rolling down an incline (even if they have identical masses) roll at different speeds. finally, be sure to respond to at least two of your peers’ posts.

You have a pick-up truck that weighed 4,000 pounds when it was new. you are modifying it to increase its ground clearance. when you are finished

How would a small bar magnet be oriented when placed at position x?

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
