Children are playing with a rope that is tied to a branch and they sue it to swing out over a lake. The starting point of the swing is 3 m above the water and at the lowest point of the swing they are just few centimeters about the water. As they continue the swing they reach the highest point again and let go, falling into the water.

a) At which point in their motion will their centripetal acceleration be the greatest? Explain.

b) What is their acceleration just as they let go of the swing?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A car is moving around a circular race track at 40 m/s in a clockwise direction. At one instant it is headed due east. In what direction is the acceleration of the car?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A cargo plane is delivering to a South Pole research station. Flying horizontally at a height of 80 m, the pilot releases a package (drops out of plane) when they are 200 m (horizontally) from the target. If the package lands on the target, how fast war the plane moving when the package was dropped?

**Theres more, but i can figure out or learn how to do these, I could probably learn how to do the others.
