- 5. Draw a distance vs. time graph for Melinda’s journey. Her home is located at 0 meters.Melinda is riding her bike over to her friend Sara’s house to complete an assignment. Her friend lives 5 km away. She accelerates away from her home for250 m in the next 2.5 minutes. She then rides at a constant speed of 300 m/min for 15 minutes. Melinda sees Sara’s house approaching so she slows downuntil she reaches her destination in the next 2.5 minutes. She stays at Sara’s house for 30 minutes while they work on the assignment. It is time to go home,Melinda rides home at a steady speed of 250 m/min for 10 minutes. Melinda is getting tired so she slows down for 250 m during the next 5 minutes thenstops for 2.5 minutes to have a drink. Realizing it’s getting late, she had to speed up 1 km in the next 5 minutes then rides at a constant speed of 300 m/minfor 2.5 minutes. Almost home, she decelerates for the next 10 minutes until she reaches her house.The velocity-versus-time graph for an object moving along an x-axis is shown below. The initial position of the object is xo = -10.0 m. V (m/s) 4- t (s) 4 0. a) Draw a motion diagram of the object. Be sure to label your velocity and acceleration vectors. 0. b) What are the position, velocity, and acceleration of the object at t = 3 s? You must show all %3D of your work to get full credit. c) Sketch the object's position-versus-time graph and acceleration-versus-time graph. 2.1. Refer to the velocity-time graph of a jogger.

- Lisa runs 1.5 km along a straight path and then turns and runs 2.4 km in the opposite direction. She then turns back and runs 700 m in the original direction. Let Lisa’s original direction be the positive direction. What are the displacement and distance, in km, she ran? * A. Displacement is 4.6 km, and distance is -0.2 km. B. Displacement is -0.2 km, and distance is 4.6 km. C. Displacement is 4.6 km, and distance is +0.2 km. D. Displacement is +0.2 km, and distance is 4.6 km.The figure shows the speedometer readings as a car drives down a straightroad. (attached) a. What is the acceleration at t = 8.0s. b. What is the change in the cars speed from 5-10 seconds? c. What distance is traveled by the car between t = 0 and t = 4 s d. Draw a graph of the acceleration for the cars motion between t=0s and t=14sWhich of the following statements are true regarding velocity-time graphs?I. The slope of a velocity-time graph is acceleration. II. The graph has a slope of zero if the object is at rest. III. A line with negative slope indicates that the object is slowing down.
- I know the answer is c but can you please explain whyA motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average speed, vavg, during this period, in meters per second? 2. What was the motorcycle's displacement in the northern direction during this period, in meters?When Sam drove at 9.5 m/s on university blvd, she passed her friend, Jess who was riding a bike at 5.0m/s. As Sam was passing Jess, she started to slow down while Jess kept her constant speed. So Jess caught up to Sam after 3 seconds. a.) Determine the distance traveled by Jess when she caught up to Sam.
- One of the most difficult things to learn in physics is that our everyday language is not always precise enough. For instance, we might say a car is “slowing down”, but that only gives us information abouts velocity, not its acceleration. What can we say about the velocity of a car which has negative acceleration in the x-direction? a. It is slowing down. b. The x-component of its velocity is decreasing. c. The x-component of its velocity is negative. d. It is speeding up. e. The x-component of its velocity is positive. f. The x-component of its velocity is increasing.How to solve this questionYou are driving at night on a straight path at 70MPH. Suddenly, a dog appears in your headlights 35 meters away. You immediatley apply the brakes which causes your car to slow down at a constant rate, coming to rest just before making contact with the dog. 1 mile = 1.61 km 1) How long did it take for your car to make a complete stop? 2) If you were initially driving in the 'positive x' direction, then what was your acceleration during the braking maneuver, in vector form and in m/s2?
