Two identical hockey pucks, each with a mass of 156 grams, are sliding along a frictionless sheet of ice. One puck is moving to the right at 12.5 m/s and the other is moving to the left at 12.5 m/s. What is the magnitude of the total momentum of the two pucks (in kg⋅m/s)?

A 1500 kg car and a 4500 kg truck are traveling down the 210 freeway. The car and the truck have the same velocity. Which one has more momentum?

Group of answer choices

the car

the car and the truck have the same momentum

the truck

You (mass 40 kg) and your friend (mass 50 kg) are both standing on some frictionless ice. You are both initially at rest. You give your friend a push and he slides to the right with a speed of 4 m/s. What is your speed after the push?

Group of answer choices

3.2 m/s to the left

5 m/s to the right

4 m/s to the left

5 m/s to the left

0 m/s
