A person is riding an elevator that is traveling downward, but slowing down at a rate of 2.25 m/s2. If this person has a mass of 60.0 kg, what is the reading on the scale that he is standing on while riding the elevator? a. 234 N b. 576 N c. 981 N d. 654 N e. 723 N 2. Which equation below is dimensionally consistent with units of acceleration? a. 𝑥2𝑡 b. 𝑣2𝑥 c. 𝑥𝑡2 d. 𝑣𝑡 e. 12𝑣𝑡2 3. Carl gets lost while hiking in the forest. Using a compass app on his phone, he decides to travel 15o north of east for 210 m. There he reaches the peak of a cliff where he is able to see everything below. He then travels 45 o south of east for another 85 m. However, his phone dies upon reaching this point, so he decides to follow his instincts the rest of the way. If Carl finds himself back where he started after traveling for another hour, what is the magnitude of his displacement during that hour? a. 263 m b. 525 m c. 314 m d. 196 m e. 227 m 4. Susan parallel-parks her car along an icy and hilly street that is inclined at angle of 30o. However, she forgets to turn on the parking-brake, and her car begins to slide down the icy street. What is the acceleration of her car? a. 6.4 m/s2 b. 5.3 m/s2 c. 9.8 m/s2 d. 7.1 m/s2 e. 4.9 m/s2UHScienceResource.squarespace.com UHScienceResource.squarespace.com 5. What is the direction of 𝐵󰇍 − 𝐴 (measured from the positive x-axis), if 𝐴 = 8𝑥 + 4𝑦 and 𝐵󰇍 = 2𝑥 + 6𝑦? a. 45o b. -20o c. 162o d. 20o e. 135o 6. A ball traveling at 2.2 m/s rolls off a table that is 1.8 m high. Just before it hits the ground, what angle below the horizontal does the velocity make? a. 34o b. 42o c. 17o d. 70o e. 85o 7. A boat is trying to cross a river that is 500 km wide to reach a dock that is directly north. However, the winds are really strong and there is a current flowing west at 15 m/s. If the boat travels at 100 m/s, what direction does it need to travel to arrive at the dock? a. 8.63o East of North b. 8.63o West of North c. 42.4o East of North d. 53.6o West of North e. 42.4o West of North 8. A car reaches 8 m/s in 5 seconds. After traveling for another 6 seconds, it reaches a velocity of 16 m/s.
