Exit Check 4.4 - Momentum Calculations

4.4.1

A baseball with a mass of 0.14kg is moving at a velocity of 40 m/s. How much momentum does it have?

Answer explanation

This question links to success criteria 4.4.1: I can use momentum to calculate a mass’ motion.

If you got it correct place a check mark in the question results section. If you got it incorrect place an X in that section. If this was a redemption question, cross out the one X and replace it with a check mark.

If two objects are traveling with the same momentum but one is going faster, which of the following must be true of the faster car?

• The faster car must have airbags

• The faster car must be experiencing more friction

• The faster car must have less mass

• The faster car must have more mass

Answer explanation

This question links to success criteria 4.4.2: I can use the relationship between momentum, mass and velocity time to determine how a change in one quantity affects the others.

4.4.2

Would it be smarter to choose to catch a bowling ball or a tennis ball traveling at 15 m/s.

• Both balls have the same momentum because they have the same velocity

• The bowling ball will be smarter to catch because it has less momentum to cancel out

• The tennis ball will be smarter to catch because it has less momentum to cancel out

• It is never smart to catch a ball.
