Ex. 5.5 A ball is tossed with a velocity of 10 m/s directed vertically upward from a window located 20 m above the ground. Knowing that the acceleration of the ball is constant and equal to 9.81 m/s? downward, determine (a) the velocity v and elevation y of the ball above the ground at any time t (b) the highest elevation reached by the ball and the corresponding value of t (c) the time when the ball will hit the ground and the corresponding velocity . Draw the v-t and y-t curves.

Ex. 5.5 A ball is tossed with a velocity of 10 m/s directed vertically upward from a
window located 20 m above the ground. Knowing that the acceleration of the ball
is constant and equal to 9.81 m/s? downward, determine (a) the velocity v and
elevation y of the ball above the ground at any time t (b) the highest elevation
reached by the ball and the corresponding value of t (c) the time when the ball will
hit the ground and the corresponding velocity . Draw the v-t and y-t curves.
