5. The Delivery Truck
A delivery truck has a mass of 3,500 kg and moves along a highway at a velocity of 15 m/s. A smaller truck has a mass of 2,000 kg and travels in the same direction at 10 m/s.
• Calculate the momentum of each truck.
• Which truck has the greater momentum, and by how much?

Answer:______________________

Answer

Work:

Momentum is calculated using the formula:

p = mv, where p is momentum, m is mass, and v is velocity.

Delivery truck:

p = (3,500 kg)(15 m/s) = 52,500 kg·m/s

Smaller truck:

p = (2,000 kg)(10 m/s) = 20,000 kg·m/s

Difference in momentum:

Δp = 52,500 − 20,000 = 32,500 kg·m/s

Answer:

  • The delivery truck has a momentum of 52,500 kg·m/s.
  • The smaller truck has a momentum of 20,000 kg·m/s.
  • The delivery truck has the greater momentum by 32,500 kg·m/s.

Both trucks’ momenta point in their shared direction of travel.
