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.
43. The giant eland, an African antelope, is an exceptional jumper, able to leap 1.5 m off the ground. To jump this high, with what speed must the eland leave the ground?

- Full formula Correct Correct Correct values answer, metric units inserted into rounded to the formula two decimal from the places word problemarrow_forwardA ball is shot vertically upward with a speed of 150 m/sec from a point 80 m above the ground. (Hint: a(t) = −9.8 m/sec²) (Round off the final answer to two decimal places.) a. How long will it take the ball to reach its highest point? b. What is the highest point it reaches? c. How long will it take the ball to reach the ground? d. What is the velocity of the ball when it strikes the ground? Garrow_forwarda. You leave your home & drive 45 km in the +y direction for a job interview. They offer you the job so you decide to stop and celebrate with friends on the way home. You leave the interview and drive 22 km in the -y direction. Let your home be your reference point. - What total distance did you drive?(km) - What total distance did you drive? ____km to the a. +y, b. -y, c. +x, d. -x, c. no direction b. You are standing on a circular track that is 400 m long. You begin jogging at the start line and keep jogging until you complete 2 full lap and stop at the same point you started at. - What is the total distance you travel? (m) -What is your final displacement? (m)arrow_forward
- A stone is thrown outward, at an angle of 65 degrees with the vertical , into the river from the edge of the cliff that is 125 meters above the wate level at a velocity of 40 kilometers per hour. Use g = 9.81 m/sec2 . 1. Determine the distance from the edge of cliff to the point where the stone drops. Answer in 2 decimal places. 2. At what height above the water level will the stone starts to fall? Answer in 2 decimal places.arrow_forwardPlease solve the 2 problems. 1. A ball rolling at a rate of 2km/hr was brought to stop in 10 seconds. Find its acceleration. Express youf answer in m/s². 2. If a person can run a distance of 20 km in three hours, what is the person's velocity. Express your answer in m/s.arrow_forward1. Is it possible that the magnitude of the speed is also the magnitude of the velocity? Explain your answer. 2. A man walked from point A to F following the route in the grid below in 250 seconds. Determine: F B. 0.5 km a. the average speed in m/s b. the magnitude of the displacement c. the magnitude of the average velocity. E. A.arrow_forward
- Helparrow_forwardWhich of the following statements are TRUE? Choose all that apply. (HINT: The statements that are false should contradict themselves or a definition.) 1. An object can simultaneously be moving and have zero velocity. 2. An object can simultaneously have zero velocity and have constant position. 3. An object can simultaneously have positive velocity and have constant acceleration. 4. An object can simultaneously have positive displacement and be traveling a positive distance. 5. An object can simultaneously be traveling a negative distance and have constant positive acceleration. 6. An object can simultaneously have positive acceleration and have positive velocity.arrow_forwardAnswer the entire problem set by using kinematic equations. Your answers must be rounded off to two decimal places. If the numerical answer exceeds 1000, do not use a comma as for 1,000. An airplane accelerates down a runway at 4.50 m/s2 for 45.6 s until it finally lifts off the ground. Determine the distance traveled before takeoff.arrow_forward
- Let's say you ride your bike from your house to your friend's house. To get there uou have to go 4.00 miles south, 8.00 miles west, then 6.00 miles north. This trip takes 32.5 minutes.a. What is your average speed for the trip in miles per minute? b. What is your average velocity for the trip in miles per minute?arrow_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_forwardPr1. The speed of a cyclist along the horizontal road is 16 km/h, 12 km/h upward and 24 km/h downward. Once the cyclist went from the village to the town, and it took 3 hours to get to the town and to go back to the village. How far is the city from the village?arrow_forward
