Which velocity graph shows the car moving toward the left (toward the origin) at a steady
(constant) velocity?
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.
The position vs. time graph of a moving particle for a time interval of 23 seconds is shown below. Each square unit in the horizontal axis corresponds to one second, and each square unit in the vertical axis corresponds to one meter.

The questions asks me to calculate the maximum height (h1), total time (t2), and speed of a ball right before it hits the ground. The question states that A person is throwing a ball upward into the air with an initial speed Vo = 10m/s. Assume that the instant when the ball is released, the person's hand is at a height ho = 1.5m. The speed of the ball at its peak height is zero, and the question needs to be solved in ascending part and descending part. I don't understand how to solve for the maximum height. What is the correct formula to use and why? For other questions like this, I will be able to solve them if I know the formulas for the ascending of the ball and the descent of the ball as well as the explanation. Thank you. For the sake of the question, the ball is being thrown straight up.arrow_forward
