A projectile fired from the ground has a velocity of 24i -8j m/s at a height of 9.8 m. Find the initial velocity and the maximum height.
Solution:
We know that and .
We can find the initial velocity in the y-direction using equation 4:
Knowing v_{yo}, we can find the maximum height, H, by setting in equation 4:
H = 13 m
