A box started at rest but was moved at a speed of 5 m/s. It was pushed 3 meters up a 60° ramp. The box weighs 5.6 kg. The coefficient of kinetic friction is 0.24. Assuming the force points up the ramp, what is the magnitude of the force?

The mass of the box is m = 5.6 kg.
The inclination of the plane with the horizontal is θ = 60 degrees.
The initial velocity of the box is u = 0 m/s.
The final velocity of the box is v = 5 m/s.
The box is moved by a distance s = 3 m.
Assume the acceleration of the box is denoted by a.
Assume a force F is applied to push the block up the plane.
Assume the acceleration due to gravity of Earth is g = 9.80 m/s2.
The coefficient of kinetic friction between the box and surface of plane is µk = 0.24.
