Hi I am in physics 1 and I need help with this problem. It saids a boy runs in an open field. He runs 233m due north in 77 seconds, turns 90 degrees to his left and runs 178m in 93 seconds. Sketch a map of his motion and find the following quantities of his motion during this period from starting time to final time
a) Map of his motion
b) The total distance he runs (233m + 178m= 411m)
c) The displacement from starting position to final position.
What I have thus far is I got c=sqrt (233)^2+(178)^2=293m. Would I subtract this number from the total distance?
Please includes detailed steps of how to solve this
I need help in calculating the average time squared.
Trial 1 = 1.20 s Trial 2 = 1.22 s Trial 3 = 1.32 s all for distance 0.3 m
I have the average time for that (1.20 + 1.22 + 1.32)/3
I would like to understand how to calculate the square of the average time so I can continue with the other distances that I have.

- The images of trees come from a catalog advertising fast-growing trees. If we mark the position of the top of the tree in the successive years, as shown in the graph in the figure, we obtain a motion diagram much like ones we have seen for other kinds of motion. The motion isn’t steady, of course. In some months the tree grows rapidly; in other months, quite slowly. We can see, though, that the average speed of growth is fairly constant for the first few years. At the end of year 3, a rope is tied to the very top of the tree to steady it. This rope is staked into the ground 15 feet away from the tree. What angle does the rope make with the ground?A. 63° B. 60°C. 30° D. 27°arrow_forwardA student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 16.5 m/s.

Andrew and Kevin decide to try out the physics ideas that they are learning and take their baseball pitching machine and a baseball to a 96 feet tall local building. Based on what they have learned the height, s(t), of a baseball, thrown straight up with an initial speed of 80 feet per second from a rooftop 96 feet high is s(t)=-16t^2+80t+96 where t is the elapsed time that the baseball is in the air.
