Homework Statement
A ball player hits a home run, and the baseball
just clears a wall 8.00 m high located 122.5 m
from home plate. The ball is hit at an angle
of 39.9◦ to the horizontal, and air resistance is
negligible. Assume the ball is hit at a height
of 1.2 m above the ground.
The acceleration of gravity is 9.81 m/s2 .
a) What is the initial speed of the ball?
Answer in units of m/s.
