WHAT WILL BE THE PROCEDURES TO GET TO THE ANSWER... THE ANSWERS ARE THE ONES IN RED

1. A box with of mass 44 kg is sliding down a ramp with an angle of 30 and a constant velocity. Calculate the friction force opposite to the motion. Ff = 215.82 N 2. A box with of mass 23 kg is sliding down a ramp with an angle of 35 and a kinetic friction coefficient of 0.4. Calculate the acceleration of the box. a = 2.41 m/s2 3. A box with of mass 18 kg is sliding down a ramp with an angle of 30 and a constant velocity. Calculate the magnitude of the normal force.FN = 152.92 N 4. Calculate the force needed to push a 60 N box upwards a ramp with an angle of 43 and constant velocity. The kinetic friction coefficient is 0.3. FA = 54.08 N 5. A skier with a mass of 80 kg is sliding down a mountain with a 12 inclination. The kinetic friction coefficient is 0.3. What force must he apply to reach an acceleration of 12 m/s2? FA = 1027.13 N
