- Tommy is working on a physics problem and asks his friend Sarah to check his work. He is to draw a free body diagram for a man walking to the left and comes up with the following: He reasons, “The man is walking to the left, so the force of friction is acting in the opposite direction. The normal force should be opposite and equal to that of the gravitational force.” Is Tommy correct with his diagram and reasoning? If so, explain. If not, what mistake did he make? Communication throughout the test will also be evaluated on 1) rounding using significant digits, 2) proper use of units, 3) organization and neatness, and 4) showing all workA 40 N box is resting on a table when a 20 N force is applied to it horizontally. The coefficients of static and kinetic friction are 0.3 and 0.1, respectively. Which of the following best describes the resulting motion of the box? The motion of the box cannot be determined with the given information. The box accelerates in the direction of the applied force. The box remains at rest. The box moves with a constant velocity in the direction of the applied force.A cart of mass 0.85 kg is on a track, connected by a string over a pulley to a hanging mass of 0.1 kg. A friction pad is attached to the bottom of the cart, and you push the cart so that it first moves toward the sensor, then away from the motion sensor. Assuming the magnitude of the force of friction remains constant throughout the entire motion of the cart, the magnitude of the net acceleration of the cart is which of the following? a. larger when the cart is moving towards the motion sensor b. larger when the cart is moving away from the motion sensor c. the magnitude of the acceleration cannot be predicted

- At a time when mining asteroids has become feasible, astronauts have connected a line between their 3360-kg space tug and a 5770- kg asteroid. They pull on the asteroid with a force of 380 N. Initially the tug and the asteroid are at rest, 356 m apart. How much time does it take for the ship and the asteroid to meet? Number Units aT apAlice and Bob had car trouble. Their car broke down and Bob could not restart it. Alice got out to push the car and after some time she asked Bob if he would trade jobs with her for a while. Bob answered, "It won't matter if I do. I took physics, and I know that no matter how hard I push on the car, it will push back on me just as hard so I won't accomplish anything. That's Newton's Third Law and it is always true. It has been tested millions of times. It wouldn't matter if I pushed the car. I wouldn't be able to push it anywhere." Aside from the fact that his relationship with Alice is probably fınished, which of the following correctly explains a flaw in Bob's logic? The third law says that the two forces he is talking about are only approximately equal. The third law does not apply in this case because the car is on wheels. O The two forces he is talking about are on two different objects. Thw two forces will not be the same because the two masses are different. The third law only…The figure shows a graph of E102 Part 1. The mass of the object is 0.696 kg. Which of the following is correct?
