A 62.0 kg curler travelling at + 1.72 m/s runs into a 78.1 kg curler and the 62.0 kg curler comes to a stop. If the 78.1 kg curler was originally moving at + 0.85 m/s, find his velocity after the interaction.

A large fish with mass 4.9 kg suddenly accelerates to a velocity 3.3 m/s to the right to gobble up a small fish with mass 0.4 kg swimming also to the right at 0.8 m/s. Immediate after the meal, how fast is the large fish? Assume the large fish didn't swallow much water.

An ice skating couple are playing in the ice. The 70 kg man gets a good start (6.0 m/s) skating toward the 55 kg woman, who is moving in the same direction at 1.5 m/s. After grabbing her hand and flinging her forward, he is still moving at 1.0 m/s in the same direction. How fast (in m/s) has he managed to get the woman moving?

Two trucks are approaching an extremely icy four way perpendicular intersection. Dennis is driving his 3100 kg truck northward at 22 m/s while Eddie drives eastward in his 1100 kg car. They collide and stick together, traveling at 59◦ north of east. What was Eddie’s original speed?

After skiding down a snow-covered hill on an inner tube, Ashley is coasting across a level snowfield at a constant velocity of +2.6 m/s. Miranda runs after her at a velocity of +4.5 m/s and hops on the inner tube. How fast do the two of them slide across the snow together on the inner tube? Ashley's mass is 54 kg, and Miranda's is 52 kg. Ignore the mass of the inner tube and any friction between the inner tube and the snow.

9. The picture below shows a rod of mass 4.50 kg which is free to rotate horizontally about one end at point O (the picture is a top view) with two forces acting on it as shown. a. What is the net torque on the rod due to the two F2 = 24.0 N F, = 12.0 N forces? b. What is the angular acceleration of the rod? If this angular acceleration remains constant and the rod is initially at rest, then what is the roď's kinetic energy 30.0% C. 2.50 m 3.50 m after 12.5 s? 10. The picture below shows a 1.75 kg box pressed against a spring whose spring constant is 275 N/m compressing the spring a distance of 0.225 m. When released the box slides along a frictionless surface and down a ramp. After reaching the bottom of the ramp, the box slides for a short distance before encountering a rough patch of floor where friction brings the box to a stop after 1.35 m. a. How fast is the box moving when it reaches the bottom of the ramp before encountering the rough patch? b. What is the magnitude of the…

After skiding down a snow-covered hill on an inner tube, Ashley is coasting across a level snowfield at a constant velocity of +2.9 m/s. Miranda runs after her at a velocity of +5.5 m/s and hops on the inner tube. How fast do the two of them slide across the snow together on the inner tube? Ashley's mass is 42 kg, and Miranda's is 78 kg. Ignore the mass of the inner tube and any friction between the inner tube and the snow. V02 Vol

An 80 kg running back moving at 5.0 m/s attempts to dive directly across the goal line for a touchdown. Just as he reaches the line, he is met head-on in mid-air by two 75 kg linebackers both moving in the direction opposite the running back at 2.8 m/s. They all become entangled as one mass. What is the velocity of the football players often the collision?

Two football players with masses of 60 kg and 50 kg run directly toward each other. The 60 kg football player runs to the east with a velocity of 5.00 m/s. The 50.kg football player runs to the west with a velocity of 4.00 m/s. If they grab each other as they collíde, what is the velocity of the players just after the collision? Your answer
