The mass of Earth is kg and its orbital radius is an average of m. Calculate the magnitude of its average linear momentum.
A skater of mass 40 kg is carrying a box of mass 5.0 kg. The skater has a speed of 5.0 m/s with respect to the floor and is gliding without any friction on a smooth surface.
Find the momentum of the box with respect to the floor.
Find the momentum of the box with respect to the floor after she puts the box down on the frictionless skating surface.
An avalanche moves a 40-cm-thick layer of snow over an area of 100 m by 500 m. The layer of snow moves distance of m down a hill in a time of 5.5 s. If the average density of the snow is 350 kg/m3, what is the average momentum of the avalanche?
