Astealth bomber is flying straight and level at a constant speed of 150 m/s at an altitude of 3500 m above the ground. it drops a bomb intended to hit a specific target on the ground.
a) how long will it take for the bomb to hit the ground?
b) at what horizontal distance away from its target must the bomber release the bomb in order to strike its target?
**disregard air resistance**

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
