You toss a ball up at 7.3m/s leaving your hand at 1.5 m above the floor. What is the balls velocity just before it hits the floor.
Is the answer 2.7 m/s
Suppose a second ball is tossed straight down at 7.3 m/s (from the same place 1.5 m above the floor). What would its velocity be just before it hits the floor?
Is it stll 2.7m/s
When would the second ball eventually hit the floor?
Is the answer 1.7 seconds.
