A 6.00-kg box sits on a ramp that is inclined at 37.0° above the horizontal. The coefficient of kinetic friction between the box and the ramp is ???k = 0.30. What horizontal? force is required to move the box up the incline with a constant acceleration of 4.20 m/s2?
Solution 66P Step 1: Mass of the box m = 6 kg Angle of inclination = 37° Coefficient of kinetic friction = 0.3 k Constant Acceleration (a) = 4.2 m/s 2
