Q. A small remote-control car with a mass of 1.7 moves at a constant speed of = 12.0 in a vertical circle inside a hollow metal cylinder that has a radius of 5.What is the magnitude of the normal force exerted on the car by the walls of cylinder at point A (at the bottom of the vertical circle)?
Q. A pendulum of length 9.00 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 3m. (That is, 3.0 m is no longer free to swing.) How long does this pendulum take for one oscillation? Suppose that all displacement angles are small.
A 59.0 kg pole vaulter running at 9.5 m/s vaults over the bar. If the vaulter's horizontal component of velocity over the bar is 1.5 m/s and air resistance is disregarded, how high was the jump.
A spring with spring constant 12.5 hangs from the ceiling. A 400 ball is attached to spring and allowed to come to rest. It is after that pulled down 6.80 and released. What is the time constant if the ball's amplitude has decreased to 3.90 after 57...
