Consider the projectile motion of two balls. Ball A is launched horizontally (no vertical component of velocity) with an initial speed of 100 m/s from an initial position 1 m above the ground. Ball B is launched straight upward (no horizontal component of velocity) with an initial speed of 1 m/s from an initial position 0.5 m above the ground. The two balls are launched at the same time. Assume that air resistance doesn’t matter in this problem and assume the ground is perfectly flat.
a) What is the horizontal component of velocity for each ball when they hit the ground?
b) What is the vertical position of ball B when it reaches its maximum height?
c) What time does ball B reach its maximum height?
d) Which ball reaches the ground first?
