Current Attempt in Progress Forces stick-block. In the figure below, a 39 kg block is pushed across a frictionless floor by means of a 3.6 kg stick. The block moves from rest through distance d = 78 cm in 1.1 s at constant acceleration. (a) Identify all horizontal third-law force pairs. (b) What is the magnitude of the force on the stick from the hand? (c) What is the magnitude of the force on the block from the stick? (d) What is the magnitude of the net force on the stick? (a) O SB = - FBS (stick and block) HS = - FSH (hand and stick) FH FHB = - FBH (hand and block) (b) Number i Units m M Frictionless surface Current Attempt in Progress Forces stick-block.
