Sassbot and Block Ness Monster play roller derby for the Reservoir Dolls, a roller derby team in Madison, Wisconsin. In a particular bout against the Unholy Rollers, another Madison team, Sassbot is playing the position of jammer: she must pass members of the Unholy Rollers in order to score points. Block Ness Monster is playing as a blocker: she must help Sassbot while also stopping the Unholy Rollers’ jammer. During a crucial moment in the bout, Monster sees that Sass, a few feet in front of her, is about to get hit by Skullz B. Kraken, a member of the Unholy Rollers. Monster reaches Sass quickly and pushes her forward, attempting to give Sass a boost of speed so she is out of the Skullz’s reach. Monster pushes Sass straight forward, delivering the push at Sass’s center of mass, her lower back, so that Sass does not experience any rotation due to the push. Neither Monster nor Sass are using their wheels to brake immediately before, during, or after the push, so the outside forces on them are negligible. Monster’s mass is 82 kg. Sass’s mass is 55 kg. Monster’s speed before the push is 2 m·s−1, and Sass’s speed before the push is 0.75 m·s−1. Monster and Sass have found, in previous practice, that the average coefficient of restitution of this sort of push between them is 0.8. The coefficient of restitution is defined as the ratio of the difference in two objects’ velocities after the collision to that of the difference in the objects’ velocities before the collision. e = v2,f − v1,fv2,i − v1,i At the moment Monster finishes her push, Skullz is 0.75 m to the left and 1.1 m in front of Sass. Skullz is moving laterally (to the right) at a speed of 2.15 m·s−1 in her attempt to hit Sass. Sass is moving directly forward after Monster’s push. Will Sass get hit by Skullz or will she get past her in time?

How long will it take Sass to travel forward past Skullz’s position?

What is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere? (2 points) it contains gases that living organisms breathe. it contains gases that trap incoming solar radiation. it provides a medium for cycles that provide nutrients to living organisms. it provides a medium for water to move between earth's surface and the air. 4. which of the following is considered a drawback to using wind energy as a source of power? (2 points) wind energy is nonrenewable. wind energy produces large amounts of air pollution. wind turbines can kill birds that fly through the rotors. wind turbines are built too close to major population centers. 5. a meteorologist predicts that the weather in a region will soon change from clear skies to probable thunderstorms. prior to making this prediction, what did the meteorologist most likely observe on a barometer? (2 points) the barometer fell slightly. the barometer fell substantially. the barometer rose slightly. the barometer rose substantially. 6. which of the following do meteorologists not typically use weather balloons to record? (2 points) atmospheric pressure cloud types humidity temperature 7. during which step in the can crush lab did water vapor force air from the can? (2 points) the can was filled nearly to the top with water. the can was placed on the hot stove top burner for several minutes. the can was removed from the hot stove top burner. the can was placed upside-down in the water-filled pan.
