If I pull a box at a small horizontal angle (say 5 degrees) with a constant force up the slope, and pull another box with the same magnitude of force (at say 60 degrees) up, will the two boxes have the same acceleration, or will one box accelerate faster? If so, which one is accelerating faster? This is a frictionless system. I can't decide if this is a trick question or not. Can I set a = F / (m * sin(theta)) with fake numbers? In that case, the angle with the smallest degree will have the highest acceleration, but is this correct?
