Coyote (mc = 12.0 kg) is about to try out his new rocket sled invention (mr = 55.0 kg), which can produce a thrust of 1700 N.What is the normal force (FN) exerted upwards by the road?If the effective frictional coefficient between the rolling wheels and the road is μ = 0.0700 what is the value of the frictional force (f)? What will be the value of the acceleration (a) while Coyote and the apparatus are in motion with the rocket firing?
