Answer:
Force is work done divided by distance
Explanation:
Work done to an object is given as rhe product of force and diatance moved, hence expressed as W=Fd where F is the applied force in Newtons, d is diatance moved in meters and W is work. The relationship between force and distance then is found by making either F or d the subject hence
hence we can say that distance is given by dividing work by force or alternatively Force is relates to distance by dividing work done by distance. Both are correct.
We can solve this problem using the law of conservation of energy.
This law states that energy in a closed system must stay same.
That means that the energy of a ball leaving the hand and the energy of a ball when it reaches its maximum height must be the same.
The energy of a ball leaving the players hand is kinetic energy:
The energy when the ball reaches its maximum height ( and has zero velocity) is potential energy in a gravitational field:
As said before these energies must be the same, and that allows us to find the initial speed:
When we plug in all the number we get that
