An object is launched at 24.5 meters per second from a platform that is 68.6 meters tall. The equation for the object's height in meters, h, at seconds after the launch is -4.9 + 2 + 24.5t + 68.6 •To find the number of seconds it will take the object to hit the ground after it is thrown, h must be set equal to 0: True or False?
•If h is set equal to 0, then t = 0 is a solution to the equation: True or False?
•The object will hit the ground at t=7 seconds: True or False?
