A wooden box containing several objects slides down a ramp at a constant speed when the ramp is inclined at 18°. The total mass of the box and its contents is 6.3 kg. A second box of equal mass slides down a different ramp at a constant speed. The second ramp is inclined at 26°. Compare the coefficients of friction of the two ramps. Explain reasoning (I need help with which forces act in certain spaces and why)
