You don’t have to do every single problem. I would just like help to get me...
Can you do 4,5,7,8 please Graph Practice Problems -v vs.t PHYS&114 Name: Use the graph below to answer questions 1-11. The graph represents the velocity of a particle as a function of time. The positive direction is right and the negative direction is left. 25 20 15 10 7 8 9 o -5 -10 -15 -20 25 time (s) 1. What is the instantaneous velocity of the particle at t-3.00s? 2. What is the instantaneous velocity of the particle at...
could u explain why 10b is AB and could you explain to me why we cant tell why acceleration has direction 10. Use the acceleration vs. time graph on the right to indicate where the line would be on the graph (somewhere in box A. somewhere in box B. either box AB, or at m/s) in the following situations. An object at rest. Acceleration vs. Time A positive velocity. A An object slowing down in the positive direction. I Time...
PLEASE ANSWER ALL QUESTION WHICH ONE IS MISSING. THANK YOU SO MUCH. ロvelocity vs. nme Graph A ball is thrown straight up into the air and then, on the way back down, is caught at the same height it was released at. For the following graphs, UP IS POSITIVE & DOWN IS NEGATIVE. Assume there is no air drag. Which one of the following vy vs. t graphs best represents the motion of the ball the entire time it was...
Help on 2 simple physics problems, just can't think about them correctly. Suppose an object starts at time t=0s at a position defined as x=0m. At t=0.5s, the object is at x=1.5m, and at t=1.0s, the object is at x=2.0m. What is the average velocity for the first interval (approximated at t=0.25s) and for the second interval (approximated at t=0.75s)? In the example above, what is the average acceleration of the object? And, he accepted value for the acceleration of...
Please show all your work. 5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...
Please Explain D, E and F. in details, because I didn't understand them. Thank you so much. Use the VELOCITY vs. TIME graph below to answer the following questions. Let south be the positive direction & north be the negative direction. Express all answers in the appropriate mks units. NOTE:m/s2 should be entered as m/s 2. VELOCITY vs. TIME GRAPH A.) Over what period of time was the object speeding up? B.) Over what period of time was the object...
i just need the second image "from the previous problem" explained 17 The position of a particle moving along the x axis is given in centimeters by x -9.751.50r3, where tis in seconds. Calculate (a) the average velocity during the time interval-2.00s to-3.00 s; (b) the instantaneous velocity at 2.00 s; (c) the instantaneous ve- locity at t-3.00s; (d) the instantaneous velocity at -2.50s; and (e) the instantaneous velocity when the particle is midway between its positions at t =...
What is the total distance traveled by the particle in meters? Thank you for your time. What Velocity vs. Time Graphs Can Tell You A common graphical representation of motion along a straight line is the v vs. t graph, that is, the graph of (instantaneous) velocity as a function of time. In this graph, time t is plotted on the horizontal axis and velocity v on the vertical axis. Note that by definition, velocity and acceleration are vector quantities....
please help me with this as fast as you can i have test and please show work The position of an object moving in a straight line is given by x = -1.5 + 3.0t - 14t^2 + 5t^3, where x is in meters and t is in seconds. (a) What is the position of the object t = 1, 2, 3 and 4 s ? (b) What is the object's displacement between t = 2 and t = 4...
Part 2: Velocity vs. Time 1. For each velocity vs. time graph (Graph 3 and 4), describe how you would walk in order to replicate the 1-D motion graph. Use words such as away, toward, at rest, speeding up, slowing down, constant speed. Be specific with your time periods. 2. For each velocity vs. time graph, create the corresponding position and acceleration versus time graphs. Construct your graph on a computer program such as Microsoft ExcelB. If you do not...
