Part a b c and d Compute the work done by gravity on the block for each segment indicated, where Wab means work done from a to b. (a) W13, (b) W12 + W23 (c) W14 + W43, (d) W14 + W15 + W53.

1) A 1.50-kg block is moved at constant speed in a vertical plane from position 1 to position 3 via several routes shown in the figure. Compute the work done by gravity on the block for each segment indicated, where Wab means work done from a to b. (a) W13, (b) W12 + W23 (c) W14 + W43, (d) W14 + Wis + W53- 3 m 40 5 3 3 mi 12 m 2
