8-75. Two trucks have a completely inelastic collision. After the
collision,
they have a common velocity of 11 m/s at 35o south of west.
Before the collision, one truck (mass 2.3x104 kg) has a
velocity
of 15 m/s at 51o south of west. Determine the initial
velocity
(magnitude and direction) of the other truck (mass 1.2x104
kg).
A "completely inelastic collision" means:
(A) The objects bounce off each
other and energy is conserved.
(B) The objects join together
and proceed as one object with combined mass and loss of energy.
