SOLUTION: Each function h (t) below represents an object being thrown upward with an initial velocity after t seconds. For each function find the time that it takes to reach the ground.

Question 999922: Each function h (t) below represents an object being thrown upward with an initial velocity after t seconds. For each function find the time that it takes to reach the ground. a)h(t)=-16t2+64t+960 b)ℎ(𝑡)= −16𝑡2 +80𝑡+576 c) ℎ(𝑡)= −16𝑡2 +64𝑡+960

the time that it takes to reach the ground:
a)

the object will reach the ground, when its height is

=> or
Only the + sign makes sense. =>
b)

=> or
Only the + sign makes sense. =>

your function c) is same as a)
