If I push a 50kg mass with an applied force of 100N, then what was the maximum kinetic friction of the mass only accelerates at 1.5m/s^2?

Respuesta :

Without friction, Newton's second law, in the form F=ma would apply.100=50a. So the acceleration should be 2m/s^2100-friction = 50x1.5100-friction = 75100-75=friction25N = friction
