Questions:
- A short punter kicks the football
from a height of 3 feet and a velocity of 65 feet per second. How long will
it take his ball to reach the ground?
Answer
- Eric
and Dan kick footballs from the same height of 4 feet. Eric’s kick has a velocity
of 65 feet per second and Dan’s velocity is 60 feet per second. Which kick
will reach the ground first, and by how many seconds?
Answer
- Say that Dan wanted his kick to
hang as long as Eric’s, even though the kick started at 3 ft. Approximately,
what would the velocity need to be (use the interactive application to find
out)?
Answer
- If you decreased the height of
the kick, would you need to increase or decrease the velocity of the kick
in order for it to take as long to reach the ground? Determine your answer
before using the interactive application. Then set the kicking height at 3
feet and change the velocity until your time results are the same as if kicked
at 4 ft. with a velocity of 60 ft./sec.
