A load of gravel is dumped straight down into a 30000-kg freight car coasting at 2.2 m/s on a straight section of a railroad. If the freight car’s speed after receiving the gravel is 1.5 m/s, what mass of gravel did it receive?
Two ice skaters stand together as illustrated in Fig. 3.28. They push off and travel directly away from each other, the boy with a velocity of 0.50 m/s to the left. If the boy weighs 735 N and the girl weighs 490 N, what is the girls velocity after they push off? (Consider the ice to be frictionless.)
Three skydivers are plummeting earthward. They are initially holding onto each other, but then push apart. Two skydivers of mass 70 and 80 kg gain horizontal velocities of 1.2 m/s north and 1.4 m/s southeast, respectively. What is the horizontal velocity of the third skydiver, whose mass is 55 kg?
