An Object Is Thrown Upward from Ground Level at a Velocity

Question 74

Multiple Choice

An object is thrown upward from ground level at a velocity of 90 feet per second. Use the position equation s = -16t2 + v0t + s0 to select a function that represents the situation and select the graph of the function.
​


A) s = -16t2 + 90t ​
​ An object is thrown upward from ground level at a velocity of 90 feet per second.
