A ball is launched from 5m up on top of a building at 60 degrees above the horizontal. On the ground, a distance away from the base of a building is a wagon that is moving at a speed of 2 m/s. The ball lands in the wagon with a final vertical speed of 12 m/s. How far from the base of the building did the wagon have to start in order to catch the ball

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
