A 80-kg person is running at 5 m/s is pushed by the wind for 20 seconds so that their velocity increases to 6 m/s. How much force does the wind apply to the runner?

your answer would be fusion

this is a good question! i'll do some research and come back when i have the answer!

the answer is b, have negligible mass

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
