A drunk man was driving his car at a speed of 25.0 m/s (or 90 kph) when he saw a cow in the middle of the road, 50.0 m away from him. It took him 0.400 s to react at which the car was moving at constant speed. After that, he stepped on the brakes to stop at a rate of 6.00 m/? . Is this acceleration enough to save him and the cow from an accident?

To help travelers get around the airport, a shuttle was built between two terminals. Starting from rest, the shuttle accelerates at 0.447 m/s2 for 37.1 s, cruises at this constent velocity for 62.5 s, and then deaccelerates at -0.275 m/s2 until it comes to a stop. What is the distance between the terminals?

Wellington Wildcat is rushing to get to a parade in time to be the grand marshal. He’s standing in theback of a flatbed truck while McFogg the Dog races at 25 m/s towards town. Suddenly, McFogg sees atiny maple leaf in the road 55 m ahead, and, being a proud Canadian, slams on the brakes to protect thesacred totem. Since McFogg is known to ride the brakes like a real jerk, let’s assume his reaction time tohit the breaks is essentially zero.A. Can McFogg actually stop before the truck reaches the leaf? The coefficients of friction betweenrubber tires and dry concrete are: μs = 1.00, μk = 0.80. When answering this question, be sure toinclude a free-body diagram representing the truck and its stellar mascots as a single object.B. Now here’s the real serious question: Is it possible for McFogg to stop short of the leaf such thatWellington does not slip and slide into the back of the truck cab? The coefficients of friction forWellington’s shoes on the bed of the truck are: μs = 0.60, μk =…
A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?
