To draw: The velocity-versus-time graph.
Answer to Problem 1CQ
The velocity-versus-time graph is drawn.
Explanation of Solution
Given data:
A person gets in an elevator on the ground floor and rides it to the top floor of a building.
Explanation:
Normally when the elevator starts to function, initially the speed or velocity will be low and then gradually increases its speed. In the middle period of the elevator functioning, the speed becomes constant and at end period speed slows down and comes to rest.
The velocity-versus-time graph for the above scenario is shown in Figure 1.
Initially graph starts from zero, gradually increases. During middle period velocity remains constant showing horizontal line in the graph. During end period there will be gradual decrease and end at zero in the graph.
Conclusion:
Hence, the velocity-versus-time graph is drawn.

- An astronaut has left an orbiting space shuttle to test a new personal maneuvering unit. As she moves along a straight line, her partner on board the shuttle measures her velocity every 2.0s starting at 2. time t=1.0s as follows: t 1.0s 0.8m/s 1.2m/s 1.8m/s 3.0s 5.0s Find the average acceleration for each time interval: a) 1s to 3s and b) 3s to 5sarrow_forwardI am having trouble with an average speed problem. The problem states that a person walks at 4.5 meters per second from point a to b. Then walks back from point b to a at a speed of 3.2 m/s. I know that average speed is displacement/time. However I am not sure how to calculate time or displacement from the two givens. The problem also gives that the average velocity is 0.arrow_forwardHonors physicsarrow_forward
- Two stones are thrown from the top edge of a building with a speed of 20 m/s, one straight down and the other straight up. The first one hits the street in a time t1. How much later is it before the second stone hits?arrow_forward1. Mario throws a stone vertically upward with a speed of 25m/s from the top of a tower 75 m high. The stone on its way down does not touch the tower. It falls straight to the ground. What is the time and velocity as it strikes the ground? 2. A piece of stone was thrown straight upward with a speed of 20.0 m/s. it was caught on its way down at a point 5 m above where it was thrown. A) How fast was it going when it was caught? B) How long did the trip take? 3. A ball is thrown at 25 m/s at an angle of 60 degrees above the horizontal. A wind blowing in the opposite direction reduces the ball's horizontal component of velocity by 6.0 m/s. How far away does the ball land? 4. A rifle bullet is fired with a muzzle velocity of 375 m/s at an angle of 30 degrees with the horizontal. Determine the a) time of flight b) maximum height reached by the bullet c) horizontal distance or range 5. A projectile with an initial velocity of 180 km/h hits the ground 180 m away from the starting point in 8.24…arrow_forwardOn your wedding day you leave for the church 30.0 minutes before the ceremony is to begin, which should be plenty of time since the church is only 10.0 miles away. On the way, however, you have to make an unanticipated stop for construction work on the road. As a result, your average speed for the first 15 minutes is only 5.0 mi/h. What average speed do you need for the rest of the trip to get you to the church on time?arrow_forward
- Marie-Philip Poulin begins from rest at one end of a 65 m long ice rink. She skates in a straight horizontal line and reaches the other end after 6.14s. She begins by accelerating with constant acceleration for 2.09 s before reaching top speed. She then continues at her top speed until she reaches the end of the rink. What is her speed when she reaches the end of the ice rink?arrow_forwardA polar bear starts at the North Pole. It travels 1.0 km south, then 1.0 km east, and then returns to its starting point. This trip takes 0.75 hr. a) What was the bear's average speed? b) What was the bear's average velocity?arrow_forwardA turtle and a rabbit engage in a footrace over a distance of 4km. The rabbit runs 0.5km and then stops for a 90-min nap. Upon awakening, he remembers the race and runs twice as fast. Finishing the course in a total time of 1.75h, the rabbit wins the race. Calculate the average speed of the rabbitarrow_forward
- A runner is training on an oval-shaped track where each lap has a length of 400 meters, the runner maintains a constant speed and completes two laps, returning to the starting point in 100 seconds. What is the velocity of the runner for this time interval?arrow_forwardYou and your family are going on a road trip to visit your recently married cousin in B.C. The total round trip distance is 2100 km. On the way to B.C., you encounter no setbacks and you are able to drive on average at a constant speed. On the way home from B.C., you encounter a snowstorm and your mom has to slow down to avoid getting into an accident. Thus, your average speed decreases by 10 km/h. If the total driving time was 42 hours, what was your average speed on the way to B.C.? Recall distance = speed x time.arrow_forwardBob is cruising leisurely on his bike at 2 m/s when Jim passes him, traveling at a constant 10 m/s. Bob immediately begins accelerating at 2.2 m/s² until he reaches his maximum velocity of 13.5 m/s. He continues cruising at that speed until he catches Jim. How long did it take him to catch up to Jim? (Assume the clock started at the instant he began to accelerate.) t = How far did he have to go to catch up to Jim? Ax = %3Darrow_forward
