it is 10 m above the ground, a package is

released from the balloon.

After it is released, for how long is the

package in the air? The acceleration of gravity

is 9.8 m/s

2

.

Answer in units of

- physics -

Subsitute in the g value and solve the equation. Take the positive root. (There will also be a negatve solution)
