A plane is flying along 550 m above the
earth with a velocity of 120 m/s when it drops a package. How long
does it take for the package to hit the ground?
If a hang glider moves with an airspeed
of 30 m/s at a 30° angle, how fast is it climbing vertically?
A cougar leaps forward from a cliff 4 m
high toward a sheep below. If the sheep is 3 m away from the base
of the cliff, what forward velocity must the cougar have to land on top
of the sheep? (Note: This is a two-step problem.)
What is the maximum height a football kicked
at a 40° angle will achieve if its initial speed is 20 m/s?
How far down the field will this same ball
travel before it hits the earth? (Note: This is a two-step problem.)
