4) A (1.4 kg) block is pushed up a frictionless (14°) incline from point A to point B by a force (P=6 N) as shown. Points A and B are (1.2m) apart. If the kinetic energies of the block at A and B are (3 J) and (4 J), respectively, how much work is done on the block by the force P between A and B (in units of J)? A) 7.2 E) 4 Solution: B) 3 C) 5.2 D) 1 $K_A = 3J$ $K_B = 4J$ $W = E_B - E_A$ $= (K+U)_B - (K+U)_A$ $W = 4 + mgh - 3$ $= 4 + 1.4 \times 10 \times 0.3 - 3$ $W = 5.2 J$
