Deep in the forest, a 17.0-g leaf falls from a tree and drops straight to the ground. If its initial height was 5.30 m and its speed just before landing was 1.3 m/s, how much nonconservative work was done on the leaf?

10. Deep in the forest, a 17.0-g leaf falls from a tree and drops straight to the ground. If its initial height was 5.30 m and its speed just before landing was 1.3 m/s, how much nonconservative work was done on the leaf? 11. A block of mass mi 2.40 kg is connected to a second block of mass m₂ = 1.80 kg, as shown in the sketch. When the blocks are released from rest, they move through a distance d = 0.500 m, at which point m₂ hits the floor. Given that the coefficient of kinetic friction between m₁ and the horizontal surface is k = 0.450, find the speed of the blocks just before m₂ lands. 7- 17 111- -h
