You car is moving along in cruise control at a constant speed of 88.3 ft/s (about 60 mi/hr).  A text message appears on your phone and you look down to read it.  When you look back up at the road, you see a car at a complete stop in your lane 156 ft ahead of you.  It takes 0.39 s for you to react and apply the brakes.  When the brakes are applied your car experiences an acceleration of -32.3 ft/s2.  Fortunately, you are able to avoid hitting the other car.  What is the distance between the two cars when you come to a complete stop? (0.9 ft).

A raindrop falls with acceleration 9.8 m/sec² , where "v" is its velocity. What is the raindrop's velocity? 29.4(1 – e3) m/sec 29.4(e- 1) m/sec 29.4(1 – e5) m/sec 32.2 (e- 1) m/sec

The bartender is totally amazing (must have studied physics). She slides your beer with an initial velocity of vo= 11.188 feet/second and the beer comes to a stop exactly in front of you after having slid a distance of d = 120.079 inches! Convert the sliding distance into proper units. d = meters meters/second Convert the initial velocity into proper units. Vo = Determine the acceleration of the beer as it slid down the counter (enter a negative number). a = Determine the time required for the beer to slide down the bar. t = seconds NOTE: The following may be helpful. . 1 foot 12 inches . 1 inch = 2.54 cm m/s²

Todd runs around the perimeter of a circular track at 8 ft/sec. The track has a radius of 80 yd. After 30 seconds, Todd turns and runs to the center of the track along a straight (radial) line. Upon reaching the center, he turns and runs away along a different radial line to his starting position on the perimeter. (a) How far has Todd traveled once he has returned to his starting position? distance = 720 v feet (b) How much time will it take for Todd to complete his circuit? time = seconds (c) Find the area of the pie-shaped sector enclosed by path. area = sq-yd
