In 2004 baseball player Adam Dunn hit the longest home run ever hit in Great American Ballpark in Cincinnati. He hit a homer which went 535 ft (163.1 m). In the following parts ignore any effects due to air resistance and assume the baseball lands at the same height it was hit.
Part A If he hit the ball at an angle of 60 degrees, what was the initial velocity of the baseball? Initial velocity =
Part B How long was the ball in the air? Time in air =
Part C What was the maximum height achieved by the baseball?
The ball is in equilibrium, with the thread making an angle of 30.0o with respect to the vertical. The area of each plate is 0.01381 m2. What is the magnitude of the charge on each plate?
A 280-kg piano slides 4.3 m down a 30o incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction is 0.40.
After 0.800, its displacement is found to be 0.13 on the opposite side and it has passed the equilibrium position once throughout this interval.

A weightlifter has been given a barbell to lift. One end has a mass of 5.05 kg while the other end has a mass of 5.20 kg. The bar is 0.20 m long. (Consider the bar to be massless, and assume that the masses are thin disks, so that their centers of ma..
Dynamics of Toboggan and Block on Ice, A 4.0 kg toboggan rests on a frictionless icy surface, and a 2.0 kg block rests on top of the toboggan. The coefficient of static friction µs between the block and the surface of the toboggan is 0.58
