Homework Statement
A ball is shot from the ground into the air. At a height of 8.8 m, the velocity is observed to be
v = (7.4)i + (5.7)j in meters per second (i horizontal, j upward). To what maximum height will the ball rise?
Homework Equations
V^2 = Vi^2 + 2a(Δy)
The Attempt at a Solution
I have listed my knowns for x and y
Y:
Yi = 0m
Y = 8.8 m
V = 5.7 m/s
Vi = 11.8 m/s ~solved from the equation
X:
V = 7.4 m/s
Xi = 0m
I am having a difficult time finding the max height because they do not give the time and I am not sure if I could solve for time with only the y components.
