A hot air balloon is ascending at the rate of 42 m/s and is 80 m above the ground when a package is dropped over the side.
(a) How long does the package take to reach the ground?
(b) With that speed does it hit the ground?
Answers
Answer:
a) h=1/2gt²
80=1/2×10×t² (taking g as 10 m/s²)
16=t²
∴t=4 s
b) v=√2gh
v²=2gh
h=v²/2g
=1764/20
=88.2 m
Yes, it hits the ground
