A 75g rubber ball moving north at 8 m/s strikes a 50g rubber ball moving south at 5 m/s.
1)
If after the collision the 75g ball comes to rest, what is the final velocity of the 50g ball?
2)
What is the maximum amount of heat and sound energy that can be produced by this collision?
Identical constant net forces act to push two identical masses
A
and
B
continuously from a starting line to a
finish line. Mass
A
is initially at rest and mass
B
is initially moving toward the finish line.
Both objects move
the same distance while being pushed.
3)
Which mass has the larger
change
in momentum?
Explain your answer.
