Abattery-operated car utilizes a 12.0 v system. initially, the car is at rest at the base of a 163 m high hill. some time later, the 690 kg car reaches the top of the hill with a speed of 25.0 m/s. how much charge did the batteries move through the motor to accomplish this, neglecting friction? note that a battery provides energy by moving charge through the battery voltage, which is 12 v in this case. (hint: the car clearly gains kinetic energy and gravitational potential energy, so that energy most be coming from somewhere. what object in this problem is the original source of that energy? )

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?
