You managed to pull a heavy crate up a ramp on a truck. The crate has mass 45 kg. You were pulling with 478 N of force along the ramp while the ramp made an angle of theta=25.5 degrees with the horizontal. The coefficient of kinetic friction between the crate and the ramp is 0.47. What is the acceleration of the crate along the ramp?
