sketch a position vs time graph and a velocity vs time graph and an acceleration vs time graph.
At time t = 0 you are walking in the positive x direction with a constant speed of 1 m/s. You maintain that speed for 6 s. Then, you decrease your speed uniformly to 0 over a 2 s interval. You rest for 2 s, then turn around and increase your speed uniformly to 2 m/s in 2 s. You continue at that speed until you return to the starting place.
An object is at x = 0 at t = 0 and moves along the x axis according to the velocity-time graph in the figure.
(a) What is the acceleration of the object between 0 and 4s? (b) What is the acceleration of the object between 4s and 9s? (c) What is the acceleration of the object between 13s and 18s? (d) At what time(s) is the object moving with the lowest speed?
In sports, the “hang time” of a player is the amount of time a player spends in the air after jumping. Most professional athletes can jump to a maximum height of 0.60 m from the ground. Use a = 9.80 m/s2 and the fact that the velocity of an object at the maximum height is 0.
1.The "hang time" is defined as the time it takes to fall from the maximum height, multiplied by 2. Find the hang time of the athlete.
2. What is the speed of the player just before they hit the ground? Express your answer in m/s and in mph.

- A stone thrown from the top of a building is given an initial velocity of 25.39 m/s straight upward. The building is 50 m high and the stone hits the ground at the bottom of the building as shown. Draw a table showing its position, velocity and acceleration at each second from start of the motion till the end. Ignore horizontal movement and person’s height. Answer the following: a) What is the maximum height reached by the stone? b) How much time does it take for the stone to hit the ground? c) What is the velocity of the stone when it hits the ground? d) Is the magnitude of velocity at horizontally adjacent points A and C the same?arrow_forwardSketch a position vs time graph, a velocity vs time graph, and an acceleration vs time graph for the situation described below.

- I 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_forwardTraumatic brain injury such as concussion results when the head undergoes a very large acceleration. Generally, an acceleration less than 800 m/s2 lasting for any length of time will not cause injury, whereas an acceleration greater than 1,000 m/s2 lasting for at least 1 ms will cause injury. Suppose a small child rolls off a bed that is 0.59 m above the floor. If the floor is hardwood, the child's head is brought to rest in approximately 1.9 mm. If the floor is carpeted, this stopping distance is increased to about 1.3 cm. Calculate the magnitude and duration of the deceleration in both cases, to determine the risk of injury. Assume the child remains horizontal during the fall to the floor. Note that a more complicated fall could result in a head velocity greater or less than the speed you calculate. hardwood floor magnitude m/s2 hardwood floor duration ms carpeted floor magnitude m/s2 carpeted floor duration msarrow_forwardI am also having trouble solving this problem since it includes the acceleration with its initial velocity without the final velocity.
