• 0.1 kg-m/s
• 1 kg-m/s
• 10 kg-m/s
• 100 kg-m/s

A biker with a mass of 75 kg moves along the path with a constant velocity of 5 m/s. What is the biker's momentum?

• 25 m/s
• 375 m/s
• 25 kg m/s
• 375 kg m/s

When the speed of an object is doubled, its momentum

• remains unchanged in accord with the conservation of momentum.
• doubles
• quadruples
• decreases

A big fish swims upon and swallows a small fish at rest. After lunch, the big fish has less

• momentum
• velocity
• mass

Which has more momentum?

• A parked semi truck

• A moving car

• they have the same amount of momentum

Which has more momentum?

• A hummingbird zipping down the street (v = 1 m/s)

• A bus stopped at a stop sign

• A bus barreling down the road (v = 10 m/s)

• A hummingbird hovering at a feeder

A bicycle has a momentum of 24 kg•m/s. What momentum would the bicycle have if it had twice the mass and was moving at the same speed?

• twice the momentum; 48 kg*m/s

• 1/2 the momentum; 12 kg*m/s

• 4x the momentum; 96 kg*m/s

• 1/4 the momentum; 6 kg*m/s

A bicycle has a momentum of 24 kg•m/s. What momentum would the bicycle have if it had the same mass and was moving with one-half the speed?

• twice the momentum; 48 kg*m/s

• 1/2 the momentum; 12 kg*m/s

• 4x the momentum; 96 kg*m/s

• 1/4 the momentum; 6 kg*m/s
