Sally is on a canoe that comes to a stop a small distance from the dock. Since it is such a small distance, Sally decides to jump to the dock. She makes the jump, but the canoe moves away from her as she jumps. Since Sally is interested to see what happens on other boats, she makes the same jump from a fishing boat that is much larger than the canoe. Which boat will move away from Sally more quickly?
a. The canoe will move away from Sally more quickly because the fishing boat is larger in mass.
b. The fishing boat will move away from Sally more quickly because it is larger in mass.
c. Both boats will move away at the same speed because Sally has not changed mass and momentum must be conserved.
d. It is impossible to predict which boat moves away from Sally more quickly.
