The 6 kg block is then released and accelerates
to the right, toward the 3 kg block. The
surface is rough and the coefficient of friction
between each block and the surface is 0.4 . The
two blocks collide, stick together, and move
to the right. Remember that the spring is not
attached to the 6 kg block.
Find the speed of the 6 kg block just before
it collides with the 3 kg block.
Answer in units of m/s.

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?
