Suppose a uniform slender rod has length l and mass m. the moment of inertia of the rod about about an axis that is perpendicular to the rod and that passes through its center of mass is given by icm=112ml2. find iend, the moment of inertia of the rod with respect to a parallel axis through one end of the rod. express iend in terms of m and l. use fractions rather than decimal numbers in your answer.

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
