A 2.5 kg mass at rest on a horizontal surface is acted upon by an applied horizontal force of 150 N. A frictional force of 150 N acts on the mass. How much work is done on the mass

Respuesta :

MathPhys

Answer:

0 J

Explanation:

Work is equal to the net force times the distance traveled in the direction of the net force. In this case, the applied force and frictional force are equal and opposite, so the net force is zero. Therefore, the work done is zero.
