This
question has 3 parts:
a. A 2 kg red
toy car begins at the right side of a long table and rolls across a table top to the middle at 1.5
cm/sec. What is it’s MOMENTUM?
b. From the left side of the table a 0.5 kg. blue toy car rolls
towards the middle at 3 cm/sec. What is it’s
MOMENTUM?
c. When these
two toy cars collide, consider these questions:
1. Which one has MORE momentum, the red
one or the blue one?
2. How MUCH MORE
momentum does it have?
3. After the collision in
which DIRECTION will the cars roll? Why?
