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. No unit is needed in your answer, it is already given in the question statement. time in seconds
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.
An object travels to the left at a constant velocity of 6m/s for 3/s and then decelerates uniformly at a rate of 1m/s^2. a) plot velocity vs time illustrating the motion of the object over a period of 10 seconds. b) using this plot, determine the displacement of the object after 9 seconds. c) what happens to the object after 9 seconds?
