When given a velocity vs. time graph, draw the corresponding position vs. time and acceleration vs. time graphs. Graphs should include labels (including numerical values and correct units) for both the horizontal and vertical axes. The values don't have to be exactly right, but they should be relatively close. If possible, find the slope and apply it to a real life situation.
A rock is tossed straight up from ground level with a speed of 30 m/s. When it returns, it falls into a hole 35 m deep. Sketch the velocity versus time graph, position versus time graph, and distance covered versus time graph. (Vertical as y-axis).
A person gets in an elevator on the ground floor and rides it to the top floor of a building. Sketch a velocity-versus-time graph for this motion.

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 4 s.

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_forwardA 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_forward
