A 4 kg eagle picks up a 75 g snake and raises it 2.5 m from the ground to a branch. What is the work done by the eagle on the snake? (Assume g = 10 m/s2) |
1.875 J 118.75 J 100 J 10 J |
1.875 J |
The work done by the eagle on the snake depends only on the mass of the snake.
Hence, the work done on the snake = (0.075 x 10 x 2.5) J
= 1.875 J.
