Two canoers, each of mass 65 kg, paddle in a single canoe of mass 52 kg. The canoe moves at a velocity of 1.5 m/s with respect to the water, in the same direction as the water. The water flows at a velocity of 3.2 m/s with respect to a stretch of land. What is the momentum of the canoe with respect to the stretch of land?
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?
A hockey puck of mass 150 g is sliding due east on a frictionless table with a speed of 10 m/s. Suddenly, a constant force of magnitude 5.0 N and direction due north is applied to the puck for 1.5 s.
Find the northward component of the hockey puck's momentum at the end of the 1.5-s interval.
Find the eastward component of the hockey puck’s momentum at the end of the 1.5-s interval.
