) A 0.0012 C charged cart is initially at rest on a ramp (1.1 m away from the bottom of theramp). At the bottom of the ramp is another charge (0.012 C). Ignoring friction, how fastis this cart (assume 100 kg) moving after it has gone 20 m up the ramp? Assume that theramp is 30 deg. from the horizontal.

An interstellar space probe is launched from Earth. After a brief period of acceleration, it moves with a constant velocity, 70.0% of the speed of light.
