Question
1. Two objects are arranged on a level, frictionless table as shown. Two experiments are conducted in which object A is launched toward the stationary block B. The initial speed of object A is the same in both experiments; the direction is not. The initial and final velocities of object A in each experiment are shown. The mass of block B is four times that of object A (mB = 4mA). a. In the space provided, draw separate arrows representing the direction of the change in momentum vector of object A in the two experiments. Is the magnitude of the change in momentum of object A in experiment 1 greater than, less than, or equal to that in experiment 2? Explain. b. In the space provided, draw separate arrows representing the direction of the change in momentum vector of block B in the two experiments. After the collisions, is the magnitude of the momentum of block B in experiment 1 greater than, less than, or equal lo that in experiment 2? If the momentum of block B is zero in either case, state that explicitly. Explain.Explanation / Answer
(a)
In two experiment block B in rest position and total momentum of system of is conserved.
So the change in momentum of object B in experiment1 is equal to experiment 2.
In two experiment block B in rest position and total momentum of system of is conserved.
So the change in momentum of object A in experiment1 is equal to experiment 2.
(b) Change in momentum direction of block B is opposite to change in momentum direction of block A.
