A student pulls a 5kg wagon with a constant speed of 1m/s along a horizontal surface. The force of friction between the wagon and the surface is 10N. What is the applied force?

  • physics -

    The speed is constant (no acceleration) so there is no net force on the wagon. Therefore the horizontal pull is 10 N to exactly balance the friction force.

    thanks!!
