5. 16t2 gives the distance in feet a free-falling object falls in t seconds.

Question

16t2 + 10t gives the distance an object falls in t seconds when it is thrown down with an initial velocity of 10 feet per second. Use this polynomials to:
Find how far a quarter thrown down with an initial velocity of 10 feet per second from a hot air balloon will travel after 5 seconds.

Answer 1

d = 16t^2 + 10t,
t = 5 seconds.
d is in feet.
