A mechanical device is used to launch a potato vertically into the air. The potato is launched from a platform 20 feet above the ground, with an initial vertical velocity of 92 feet per second
The function h(t) = -16t^2+ 92t + 20 models the height of the potato over the ground, in feet, t seconds after launch,
Here is the graph representing the function.
Part A
1. What is the height of the potato 1 second after launch?
2, 8 seconds after launch, will the potato still be in the air ?
3, Will the potato reach 120 feet? If so, when will it happen ?
4. When will the potato hit the ground?
