A box is pushed up the ramp by the horizontal force shown. The mass of the box is M and the pushing force is Fo. The coefficient of kinetic friction is 0.3 and that of static friction is 0.5. How large is the kinetic friction force? Don't guess. Draw the free body diagram and use the free body diagram method.

You stand on a scale and then push off to jump. The scale reads 112 kg when the acceleration of your center
of mass during is 17 m/s?. What did the scale read when you stood stationary on the scale? Answer in kg.
Note your center of mass is accelerating upwards but your feet are still contact with the scale.
Don't guess. Use the free body diagram method.
Use g=10 m/s² if you need g.
