Concept explainers
Problems 39 through 45 are motion problems similar to those you will learn to solve in Chapter 2. For now, simply interpret the problem by drawing a motion diagram showing the object's position and its velocity vectors. Do not solve these problems or do any mathematics.
44. A ball rolls along a smooth horizontal floor at 10 m/s, then starts up a 20° ramp. How high does it go before rolling back down?

- Monarch butterflies belong to one of the most beautiful species of animals. To protect themselves from the cold in Canada and the United States, they fly to Mexico and the countries of Central America in the fall. If they travel an approximate distance of 3,960 km during 60 days, a) what is the speed of the butterflies in m / s b) in km / hrarrow_forwardHi I need to learn how to solve this with part A B C and D please I’m really stuck if you can help me, thank you A) sketch the situation given in the problem. B) equation of the problem. C) Numeric solution D) unit check and number check. How can I know A B c Darrow_forwardDwight decides to race around the perimeter of the Scranton business parkin an effort to beat another employee’s best running time. Assuming heruns with an average velocity of 10 ft/s, and he completes 4 laps in 5minutes,a. What is the perimeter of the business park in feet?b. In meters?( 1 ft = 0.3048 m )arrow_forward
- 1."An airplane accelerates down a runway at 3.20m/s2 for 32.8s until it finally lifts off the ground. how long is the said runway? how long is the said runway?" From the problem, what is the most appropriate equation to be used? 2.Which describe the velocity of an object upward? a.The object moves in constant velocity for one meter b.The object adds one meter per second squared in its velocity every second c.The object changes its velocity to one meter per second at its highest point d.The object adds one meter per second in its velocity every second 3. which tells how fast an object is moving? a.30km at 40 northeast b.60 miles per hour in 4 hr c. 30 meters per second d. 30 meter per second squaredarrow_forward1. The boy walk 76 km east and run in the direction of 12 km north in 40 second. a. What is the boy's distance? b. What is the boy's displacement? c. What is the boy's speed? Formula speed distance/time d. What is the boy's velocity? Formula velocity displacement/timearrow_forwardA person drops a rock from the edge of a cliff that is 1350 ft high. The initial acceleration is a=−32 ft/sec^2. 1. What is the velocity equation? Use t as the variable and v for the velocity. 2. What is the displacement equation? Use t as the variable and s as the displacement. 3.What time did it hit the ground? (Hint: s=0) 4. What was the velocity just before impact?arrow_forward
- A car goes 78 m to the righty and then 22 m to the left. It makes this trip on 35 seconds. a. What is the displacement in meters? b. What is the total distance travelled in meters? c. What is the average velocity? d. What is the average speed in m/s?arrow_forwardDear, Can you please solve this for me with extra explanations and drawing to understand the answer better as I have an exam soon? Thank you in advance and Merry Christmas!arrow_forwarda. Supposed that this is a motion plot of a car. What is the velocity of the car? b. Supposed that this is a motion plot of a car. What is the acceleration of the car?arrow_forward
- Hi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please break it down so I can understand. I tried to solve it how you guys did it but I keep getting another answer. Thank you!arrow_forward"A jet plane is cruising at 320 m/sm/s when suddenly the pilot turns the engines up to full throttle. After traveling 4.8 km , the jet is moving with a speed of 400 m/sm/s. What is the jet's acceleration, assuming it to be a constant acceleration? Express your answer to two significant figures and include the appropriate units." I am having issues setting up word problems to begin solving. Need an easier method or technique to help deciper these.arrow_forwardTo get to his office from home, Greg walks 5 blocks north and then 2 blocks east. After work he meets some friends at a cafe; to get there he walks 3 blocks south and 6 blocks west. All blocks are 660 feet long. What is the straight-line distance from the cafe to his home? Express your answer in feet.arrow_forward
