Somebody explain how to solve this. in advance! use the formula for work. order the work done in the following situations from least to greatest. -a 2000 kg car travels 400 m down a road -a cannon launches a 3 kg cannonball a distance of 200 -a farmer pushes a 2 kg wheelbarrow 20 m -a flea pushes a speck of dirt 1 cm -a man exerts strenuous effort in pushing a stationary wall -space shuttle atlantis launches from the ground into near-earth orbit

work done is product of force and displacement of point of application of force

so here we have to check the product of force and displacement both

Now we will put the least to maximum work in the following order

1. -A man exerts strenuous effort in pushing a stationary wall

2. -A flea pushes a speck of dirt 1 cm

3. -A farmer pushes a 2 kg wheelbarrow 20 m

4. -A cannon launches a 3 kg cannonball a distance of 200

5. -A 2000 kg car travels 400 m down a road

6. -Space shuttle Atlantis launches from the ground into near-Earth orbit

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
