In the Marvel comic series X-Men, Colossus would sometimes throw Wolverine toward an enemy in what was called a fastball special. Suppose Colossus throws Wolverine at an angle of θ = 23.0° with respect to the ground. Wolverine is d = 2.05 m above the ground when he is released, and he leaves Colossus's hands with a speed of vi = 22.6 m/s. (a) Using conservation of energy and the components of the initial velocity, find the maximum height attained by Wolverine during the flight.
m

(b) Using conservation of energy, what is Wolverine's speed the instant before he hits the ground?
m/s
