Afullback having a mass of 9.0x10^1 kg is running at 4.5 m/s [e]. he is hit by a linebacker and 1.2 s later is moving backwards at 1.5 m/s [w].find:
a) the impulse imparted to the fullback b) the average force exerted on the fullback by the linebacker
my work: impulse is p so p= p2-p2 p=m2v2-m1v1 but its all wrong because the answer is 5.4 x 10^2 kg. m/s [w] apparently. !

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?
