Problem $4.$NEED NUMBER FIVE ANSWERED PLEASE

A basketball player is shooting hoops. How much MECHANICAL WORK must the player perform on the ball to achieve a release velocity of $7\mathrm{.}83\frac{m}{s}?$ Release velocity is the speed of the ball the instance the ball leaves the player's hands. The mass of the ball is $0\mathrm{.}62$ kg $.$

Problem $5.$

The same player from Problem $4$ is now running down the court at a speed of $5\frac{m}{s}.$ While running, the player shoots the ball in an attempt to make the basket. The player aced the subject of kinematics in school and knows that if they shoot the ball straight up at a certain vertical velocity, the ball will land in the hoop. What is the magnitude of this vertical velocity? The effect of air resistance on the ball can be ignored.
