When a ball is thrown vertically upward from a reference location, it travels to a maximum height and then changes direction and experiences a fall. Ignoring the air resistance and a number of other tiny influences, the location of the ball (H) and its velocity (V) at time ( t) can be expressed by the following expressions:tgVoV)(2)2/()(tgtVoH Here Vois the initial upward velocity, gis the earth gravitational acceleration (9.81 m/s 2)and His measured upward from the reference location. Usingthe above expressions one can find the time(tm) it takes for the ball to reach its maximum height(Hm) and the time it takes for the ball to return to its reference location (tr) as listed below:gVotm/)2/(2gVoHmgVotr/2Wri te a program to:1.read the initial velocity of the ball from the keyboard and calculate tm, Hm, and trand then print their values with appropriate labels. Test the program for Vo= 100 m/sec.2.read a value for the time and calculate the corresponding velocity and the height of the ball and print their values with proper labels(use Vo= 100); test the program for t= 15 sec.
