A motorcyclist is traveling at a constant speed of 60 miles per hour when he sees a jackknifed tractor trailer blocking the road. His brakes impart to the motorcycle a constant negative acceleration of 20 feet per second per second. If he is 200 feet feet from the tractor when he applies the brakes, will he be able to avoid a collision? If so, how far from the trailer will he be when he comes to a stop? If not, at what speed will he hit the trailer? (Warning: Pay attention to the units.) 5. An object moving in a straight line has velocity function v ( t ) = 25( t5) 2 , for 0 t 5, where velocity is measured in ft/sec and time in seconds. Using subintervals of 1 seconds each, nd upper and lower approximations of the distance traveled by the object....
