Problem
On a planet far, far away, some misbehaved students threw an object out of a window, located h=40m above the ground. It landed after t=4s. How much would this object weigh on Earth, if the gravitational force acting upon the object on the distant planet is F=55N? Consider the gravitational field to be constant on both planets and the air drag to be negligible.
