A block of mass 2kg is projected upwards with speed 10 m/s & stops momentarily at height of 4m & returns with speed of 8 m/s. (consider air resistance is present and take g=10m/s² Work done by air resistance in ascending motion is -20 J Work done by air resistance in descending motion is -16 J Total work done by air resistance is 38 J Total work done by air resistance is -38 J
