A cat walks in a straight line, which we shall call the -axis, with the positive direction to the right. As an observant physicist, you make measurements of this cat's motion and construct a graph of the feline's velocity as a function of time (Figure 1). I. Calculate the area under the graph between t = 0 and t = 6.0 s. (Express your answer to two significant figures and include the appropriate units.) II. For the time interval t = 0 to t = 6.0 s, what is the magnitude of the average velocity of the cat? (Express your answer to two significant figures and include the appropriate units.) III. Use constant-acceleration equations to calculate the distance the cat travels in this time interval. (Express your answer to two significant figures and include the appropriate units.)

A Ford Mustang can accelerate from 0 to 60 mph in a time of 6.0 s. A Mini Cooper isn't capable of such a rapid start, but it can turn in a very small circle 40 ft in diameter. Part A How fast would you need to drive the Mini Cooper in this tight circle to match the magnitude of the Mustang's acceleration? Express your answer in miles per hour. V= 5 ΑΣΦ mph
1 of 1 1114 (Page) Assignment#8 (due Monday July 12th by 11:30am) Each assignment will contain questions to be handed in for marking. Remember that to get full marks on a problem you must include diagrams, coordinate systems etc. You must show your work to receive marks. Include a diagram and co-ordinate system as needed. Note: as stated on the course outline, only a selection of the problems may be marked for credit so DO ALL THE QUESTIONS as you do not know which ones will be marked. Questions: 1. (2.2 from text): What is the average density of the earth? The earth has a mass of 5.98 x10" kg. The average diameter of the earth is 1.27 x 10' m. Assume the earth is a sphere. Compare this density to the density of water. (Ans SS 10/m) 2. (3.4 from text): The density of ice is 9.20 x 10 kg/m'. An ice cube which is 20.0 mm high floats in water.
