Physics

A boy standing on the ground close to a building throws a ballvertically upward. From his measurements of the maximum height,y-max, to which the ball rises and the time required to reach thisheight, the boy calculates that the average velocity of the ball onits way up is 20 m/s. Five seconds after leaving the boys hand, theball is caught by a girl who has stretched her arm out of a windowsome distance above the boy. You may use -9.8 m/s^2 for the valueof g.
a. What is the velocity of the ball immediately after itsrelease?
b. How high does the ball rise; i.e., what is the value ofy-max?
c. At what height, y, above the point of release is the ballcaught?
d. What is the velocity of the ball immediately before beingcaught
