A machine is used to cause an object to move along a curved path with a radius of 1 ft. The object has a mass of 5 lbm and it is subjected to a force of (F = 2t + 1)lbf, where t is in seconds. Find the change in momentum of the object after 3 seconds if it was initially traveling at 2 ft/s. Answers: 386.09 lbm-ft² S
