Julie throws a ball to her friend sarah. the ball leaves julie's hand a distance 1.5 meters above the ground with an initial speed of 16 m/s at an angle 47 degrees; with respect to the horizontal. sarah catches the ball 1.5 meters above the ground.

what is the maximum height the ball goes above the ground?

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
