An airline pilot pulls her 12.0 kg rollaboard suitcase along the ground with a force of 25.0 N for 10.0 meters. The handle she pulls on makes an angle of 42.5 degrees with the horizontal. How much work does she do over the ten-meter distance?

Tried doing: (Cos(42.5) * 25N) * 10 = W

Didn't seem to work though?

1 answer

W = (25*cos42.5) * 10 = 184.3 Joules.
