As you are headed to class, your friend leans out the window of your apartment 10 m above you and shouts that you took her car keys rather than your own. Since you are in a hurry, you decide to toss your friend's keys up to her while she drops your keys down to you.You throw the keys just hard enough to reach her outstretched hand. At what height above you will the two sets of keys pass each other?

A group of students celebrate their first year of medical school with a hot-air balloon ride, which is rising upward with a constant speed of 3.0 m/s. When the balloon is 3.50 m above the ground, one of the students who is taking a selfie with the other students accidentally drops her smart phone over the side of the balloon (fortunately with a OtterBox case). With what speed would the phone hit the ground in m/s? Note that the displacement of the phone dropping 3.50 m would be - 3.50 m. For the same situation as Question 9, how long in seconds would the smart phone be in the air before it hits the ground?

The red ball hits the ground with the greater speed.b. Both balls hit the ground with the same vertical velocity component.c. Both balls hit the ground with the same angle of impactd. The balls reach the ground at the same instant. More than one of the statements can be true.

A distance of 60 meters separates two jetskis at Virginia Beach. Starting at rest, the jetskis accelerate at a constant rate of 0.2 m/s2 towards each other.Starting at a midpoint between the two jetskis, a porpoise is seen swimming from one jetski to the other at a constant speed of 16 m/s. The porpoise continues swimming back and forth between the jetskis until they crash together.a) What is the total distance the porpoise travelled? b) what is the speed of the jetskis when they crash together?

Speedy Sue, driving at 32.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 175 m ahead traveling at 5.30 m/s. Sue applies her brakes but can accelerate only at −1.10 m/s2 because the road is wet. Will there be a collision? If yes, determine how far into the tunnel and at what time the collision occurs. If no, determine the distance of closest approach between Sue's car and the van. (If no, enter "0" for the time.)
A certain volcano on the Earth can eject rocks vertically to a maximum height H.
