A package is thrown downward with an initial velocity of -5 ft/sec from a helicopter at 300 ft. A) what is the height of the package in 2 sec? B) how long does it take to hit the ground?

Round answer to 2 decimals Enter: blank ft,blank sec.

**Henry**, Tuesday, May 1, 2012 at 7:11pmA. h = ho - (Vo*t + 16t^2).

h = 300 - (5*2 + 16*2^2 )= 226 Ft above

gnd.

B. h = 300 - (5t + 16t^2 = 0.

300 - 5t -16t^2 = 0.

-16t^2 - 5t + 300 = 0.

Use Quad. Formula>

t = 4.18 s.
