Question

Maria throws an apple vertically upward from
a height of 1.3 m with an initial velocity of
+2.6 m/s.
Will the apple reach a friend in a tree house
2.4 m above the ground? The acceleration
1. No, the apple will reach 1.37063 m below
the tree house
2. Yes, the apple will reach 1.37063 m above
the tree house
3. Yes, the apple will reach 0.755454 m
above the tree house
4. No, the apple will reach 0.755454 m
below the tree house
5. Yes, the apple will reach 1.48537 m above
the tree house

Answer 1

h = -.5 g t^2 + 2.6 t + 1.3

the max height occurs at the value of t that lies on the axis of symmetry (t = -b / 2a) __ t = -2.6 / -9.8

find t and substitute back to find the max height
