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

Explanation:
using the first eqn for motion
The answer to this question is A.
As per conditions described here we know that all force arrow are not of equal length
So all forces are not same in magnitude
Here applied force on right direction is more in magnitude then the friction force on left
So it will have net unbalanced force towards right due to which it will move towards right direction or in the direction of net unbalanced force
While in the upward and downward direction the forces are balanced and hence the box will not move in that direction
So normal force will be balanced by gravitational force
So here answer will be
The forces acting on the box are <u>UNBALANCED</u> .
The box will move to the <u>RIGHT</u> .
