1) A tennis ball is thrown vertically downward from a height of 54 feet with an initial velocity of 8 feet/second. What is its impact if it hits a six foot tall man on the head?(a(t)=-32)

2) A projectile is shot vertically upward from ground level with an initial velocity of 49 meters per second. Use a(t)=-9.8 m/sec^2

A) what is the maximum height obtained by the projectile

B) what is the velocity at impact>
