Answer to Question #6375 in Mechanics | Relativity for Allie
A 6 Kg cart on a level surface is pulled at a constant velocity of 2 m/sec by a constant force of 10 N. What is the acceleration? What is the friction force opposing the motion?
As the car is pulled at a constant velocity, the acceleration and vector sum of the forces acting on the car equals to zero.
Thus a = 0; F - Ffrict = 0; Ffrict = 10 N.
