A ferrari with 808 hp has a max. speed of 211 mph at 6,300 rpm. the Ferrari weighs 4,155 lb/ton and is operated over a smooth concrete road with a rolling resistance of 40 lb/ton and a slope of 3%. Determine the maximum external pull the Ferrari has when operated in sixth gear at maximum speed.
The velocity of a particle traveling along a straight line is v=(3t^2-6t) ft/s , where t is in seconds. if s=4ft when t=0 determine the position of the particle when t=4s what is the total distance during the time interval t=0 to t=4s
