Compare the momentum of a truck at rest and a moving skate and find out which one is higher.
A wad of chewed bubble gum is moving with 1 unit of momentum when it collides with a heavy box that is initially at rest. The gum sticks to the box and both are set in motion with a combined momentum equal to?
a truck going 15 km/h has a head-on collision with a small car going 30 km/h.
A truck going 15 km/h has a head-on collision with a small car going 30 km/h.
1. The car has the greater change of momentum because it has the greater speed.2. The truck has the greater change of momentum because it has the greater mass.3. They both have the same change in magnitude of momentum because momentum is conserved.4. Neither the car nor the truck changes its momentum in the collision because momentum is conserved.5. None of the above is necessarily true.
