A ball is thrown vertically upward from the top of the house 112 ft high with an initial velocity of 96 ft/sec. a. Write an equation of motion of the ball using the equation s = -16t2 + vot + so where s feet is the height of the object at t sec, so feet is the initial height of the object and vo ft/sec is the object's initial velocity. b. How high will the ball go and how long does it take reach its highest point? c. How long does it take for the ball to reach the ground?

Question
A ball is thrown vertically upward from the top of the house 112 ft high with
an initial velocity of 96 ft/sec.
a. Write an equation of motion of the ball using the equation s =
where s feet is the height of the object at t sec, so feet is the initial height of the
object and vo ft/sec is the object's initial velocity.
b. How high will the ball go and how long does it take reach its highest point?
c. How long does it take for the ball to reach the ground?
d. Find the speed of the ball at 2 sec and 4 sec.
e. Find the instantaneous velocity of the ball when it reaches the ground.
-16t? + vot + So
