The following graph depicts the velocity of someone playing tag over a short period of time. Use this velocity graph to answer the following questions. The person's maximum magnitude for velocity is 4.5 m/s in both the positive and negative directions.  A is at time point 3 seconds, B is at time point 4.5 seconds, C is at time point 5.5 seconds, D is at time point 7 seconds, E is at 8 seconds, F is at 9 seconds and G is at 10 seconds. What is the acceleration in meters/second2 (m/s2) at the 2 second mark of playing tag? What is the acceleration in meters/second2 (m/s2) at the 5 second mark?  What is the velocity in meters/second (m/s) at the 5 second mark?  What is the acceleration in meters/second2 (m/s2) at the 6.5 second mark?  What is the acceleration in meters/second2 (m/s2) at the 8.5 second mark?  What is the velocity in meters/second (m/s) at the 9.5 second mark?

A ball is thrown straight down at 1.29 m/s and hits the ground 1.07 seconds later. How many meters did the ball travel before hitting the ground? Type your answer.

I have no clue why this problem is being rejected. I have submitted similar problems and have been answered. Can I please get some help with this. Thank you!

A physics teacher walks 5 km East, 2.5 km South, 5 km West, and finally 2.5 km North. The entire motion lasted for 3 hours. Determine the average speed and the average velocity.

Shown below is a graph of velocity-versus-time for a moving object. The object starts at position x = 0 m at t = 0 s. What is the final position at t = 4.0 s, in meters?

The figure shows three graphs, A, B, and C, which collectively describe the motion of an object in one dimension. The horizontal axis of each graph is time (symbol t). The vertical axes of the graphs are different. For one graph the vertical axis is position (symbol x), for another it is velocity (symbol v), and for another it is acceleration (symbol a). Where the axes cross is the point of zero for both time and the quantity corresponding to the vertical axis. Part A:  For which sequence of graphs is the vertical coordinate position, velocity, and acceleration, respectively? (e.g., If you think graph Y is position versus time, graph X is velocity versus time, and graph Z is acceleration versus time, then your answer is Y, X, Z.). Multiple choice:  1)C, A, B 2)A, C, B 3)C, B, A 4)B, C, A 5)B, A, C 6)A, B, C. Part (b) Which one of the following situations can be most accurately represented by the graphs, consistent with your answer to part (a)? (1) A car driving in the negative x…

Figure below shows the position of a cart moves along the x-axis. What is the object's velocity at 2.0 s, in m/s? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. x (m) 2 1 A K 0 T -1 -2 B 2 4 6 8 10 C D 12 14 X6 E 18 -t (s)

The figure shows an acceleration- time graph of a particle with a starting velocity at 60 m/s and the distance travelled is 200 meters at 10 seconds. Draw the (v-t), and (s-t) graphs of the particle. Determine the total distance travelled and its velocity at 18 seconds. 4m/s? 10s te14s t= 18s Am/s
