A 40 lb object is subjected to an applied upward force of 20 lbf. The only other force acting on the object is the force of gravity. The acceleration of gravity is 32.2 ft/s². Determine the weight of the object, in lbf, and the net acceleration of the object, in ft/s². Step 1 Your answer is correct. Determine the weight of the object, in lbf, with positive values being down. W = 40 lbf Hint Step 2 X Your answer is incorrect. Determine the net acceleration of the object, in ft/s², with positive values being upward. ft/s² a= 16.1 Attempts: 1 of 3 used
