All bodies with mass are attracted to the Earth by gravity, so when a body is raised you must do work to raise it. This work is equal to force x height, if force is in Newtons and height in meters, the work is in units of Joules.
It depends on the magnitude of the force and the mass of the object
Just use the formula for gravitational potential energy:GPE = mgh Where m is the mass, g the gravity (around 9.8, in SI units), and h the height.
Work Done = Force x Distance = Power / Time = (Force x speed)/Time
The work done on an object is w= (f)orce.(d)istance = fd.

Force on the box = (weight) = (mass) x (gravity)Work = (force) x (distance) = (mass x gravity) x (distance)Mass = (work) / (gravity x distance)= (5000) / (9.8 x 16) = 31.888 kg (rounded)
mgh or (1/2)mv2

power=work done/time interval
Work Done = Force x Distance = Power / Time = (Force x speed)/Time

Yes, throwing the ball requires a force, and work is done when a force moves a mass over a distance.
