A moped is moving at a constant speed v when it happens upon a circular hill of radius r=549m. The operator and moped combined have mass m=153kg. The drawing below is not to scale. What speed in, in meters per second, does the moped have if the operator feels weightless, i.e., has an apparent weight of zero, at the top of the hill. If the operator is moving at the speed above and happens upon a hill with a radius 2r, then what is the apparent combined weight, in newtons, of both the operator and the moped at the top of the hill

A cue ball of mass m1 = 0.39 kg is shot at another billiard ball, with mass m2 = 0.585 kg, which is at rest. The cue ball has an initial speed of v = 6.5 m/s in the positive direction. Assume that the collision is elastic and exactly head-on. Write an expression for the horizontal component of the billiard ball's velocity, Vf2, after the collision, in terms of the other variables of the problem

The mass of a particular skateboard plus its rider is ms=71.6kg , and the skateboarder is holding a book with mass mb=2.62kg . Initially at rest, the skateboarder tosses the textbook with a velocity of vb=2.44m/s at an angle θ=29.8∘ above the horizontal, and the book is caught by a friend. What is the magnitude, in newton seconds, of the momentum, pE , which was transferred to the the Earth during the time the book was being thrown? pE =
