1. How far away will a ball land when thrown from a hill 70 m high at a 45 angle from the horizontal at an initial velocity of 9 m/s?
2. How long will it take for the ball in problem 1 to fall to the ground? Remember the pull of gravity is (-9.8 m/s)
3. What is the maximum height reached by the object?

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
