The following questions refer to the velocity versus time graph shown below. Assume that v>0 for eastward motion and v<0 for westward.(Graph Description: The graph plots velocity (v in m/s) on the y-axis against time (t in seconds) on the x-axis. It starts at v = -10 m/s at t = 0 s. The velocity line increases linearly to v = 20 m/s at t = 2 s, maintains this speed level until t = 5 s, then decreases linearly to v = 10 m/s at t = 6 s. It then stays constant until t = 9 s and finally goes back to v = 0 m/s at t = 10 s.)1. During what time was the object moving eastward at the greatest speed?2. Describe how did the object's speed change at exactly t = 2.0 s (i.e. what was happening immediately before and after t = 2.0 s?).3. Find the average acceleration of the entire trip.4. Draw an acceleration vs. time graph.

QUESTION 12 A rest observer is measuring the velocity of an object that is moving with a constant acceleration In 1D. At t1=0 s, the observer measures velocity of the object is 18 m/s. At t2-12 s, the observer measures velocity of the object is 97 m/s. what is the distance not required to include the unit in your answer)? (Note: For fill in blank, I have set the unit for the answer. So, you just need to provide a number - Please write your numerical answer with all digits and do not use scientific notation.

A motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average velocity in in the northern direction vavg,N, in this period in meters per second? 2. If the motorcycle's final velocity at tf was 12 m/s, what was the motorcycle's average acceleration in the northern direction, aavg,N, during this period in m/s2?
Figure below is a velocity-versus-time graph for a moving object. The object starts at position x = 0. What is the acceleration at t= 1.0 s, in m/s2? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive.

6. A train is moving with a constant speed. The train moves 60 meters for every 1.5 seconds that elapses. a. Assume that we get 40 by dividing 60 by 1.5. What is the name that is commonly given to a quantity represented by this number 40? b. To denote the quantity completely, what additional information must be given besides the number 40? c. How would you interpret the number 40 in this instance? Your answer should mention distance and time. d. Use your interpretation (not algebra) to find the distance the train moves in 2.5 seconds.
