A 10-kg wooden box rests on a wooden ramp. The coefficient of static friction is 0.50, and the coefficient of kinetic friction is 0.30. What is the friction force between the box and ramp if
the ramp is at a 25o angle?
the ramp is at a 45o angle?
what is the acceleration of the box when the ramp is at 45o?
