2. (a) Explain the difference between constant velocity and constant acceleration. (b) Are you more likely to be able to walk at a constant velocity or at constant acceleration? (c) For the equation x = Xo + of + at, what does a graph of x versus t look like? (d) What does the graph look like if a -0? Please scetch graphs and give explanations. (7 pts) 2 3. For the following position versus time values, calculate the average...
A graph of position versus time for a certain particle moving along the x-axis is shown in the figure below. Find the average velocity in the following time intervals. (a) 0 to 2.00 s m/s (b) 0 to 4.00 s m/s (c) 2.00 s to 4.00 m/s (d) 4.00 s to 7.00 s
Learning Goal: To learn to read a graph of position versus time and to calculate average velocityIn this problem you will determine the average velocity of a moving object from the graph of its position z(t) as a function of time t. A traveling object might move at different speeds and in different directions durina an Now find vave [0,3].Find the average velocity over the time interval from 3 to 6 seconds
2. Calculate the velocity at each time (except the first and the last one) by using values immediately after and before those times: the tn-- For example, the velocity at point 2 is n Time t (s) Position x (m) Velocity v (m/s) vt (unit-mls) aGou .245 8 3,abus 1.553 3. calculate v/t (what are the units?) and write it in column 5 of the table above. Calculate its average and its uncertainty: Average uncertainty: 4. On the graph paper,...
The position versus time for a certain particle moving along the x axis is shown in Figure P2.3. Find the average velocity in the following time intervals. (a) 0 to 6s m/s (b) 0 to 7 s m/s (c) 2 s to 4s m/s (d) 4 s to 7 s m/s (e) 0 to 8 s m/s

Problem 7. Below you are supplied a position versus time graph. Draw velocity versus time and acceleration versus time graphs consistent with this position versus time graph. Assume that this is one dimensional motion along the x axis, that you are standing on the origin (x = 0) with positive x off to your right and negative x off to your left. Describe the motion of the object in everyday terms without using the words velocity, acceleration, slope, positive or...
