Assume that the maximum horizontal distance you can throw a baseball (m = 0.145 kg) at an angle of α0 = 45∘ above the horizontal is 25 m. Part A) What is the kinetic energy of the baseball just after it leaves your hand? Ignore air resistance and the small distance the ball is above the ground when it leaves your hand. Take the zero of potential energy to be at the ground. Part B) At the ball's maximum height,...

A ball of mass 0.083 kg is shot straight up in the air using a compressed spring. The spring has a spring constant of 328 N/m and is compressed by 0.05 m initially. The ball reaches a height of 0.252 m above the initial position. How much energy has dissipated due to frictional effects such as air drag ? (in J)

You throw a frisbee of mass m = 0.5 kg, and radius
r = 0.1 meters, off of a hill, with initial translational
speed of v0 = 5 m/s, from a height of
h0 = 3 meters. The tangential speed of the edge
of the frisbee is equal to the initial translational speed, and
doesn't change as it travels through the air. Treat the frisbee as
a solid disk, and ignore air resistance.
