Entrance and exit ramps for freeways in (Figure 1) are often circular stretches of road. As you go around one at a constant speed, you will experience a constant acceleration. Suppose you drive through an entrance ramp at a modest speed and your acceleration is 3.5 m/s?. Part A What will be the acceleration if you double your speed? Express your answer with the appropriate units.

Q Next diagram shows relationship between aelocity and time of a body moving along shown path. Let me see physical touches in your answer, not just mathematical notes. O Find the average acceleration of the object during the time intervals (0-5) .

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.)

The answer for this problem would be "C" but could you explain me why? The reason for this is to understand this kind of problems in the future not only this one.

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
