Joyce and Efua are skating. Joyce pushes Efua, whose mass is 40 kg, with a force of 16 N. The force of friction between Efua's skates and the ice is 2 N. What is the magnitude of the net force exerted by Joyce on Efua?
To find the magnitude of the net force exerted by Joyce on Efua, we need to consider the force of friction as well. The net force is determined by subtracting the force of friction from the applied force.
1. Determine the net force:
Net force = Applied force - Force of friction
2. Substitute the given values:
Applied force = 16 N
Force of friction = 2 N
Net force = 16 N - 2 N
Net force = 14 N
Therefore, the magnitude of the net force exerted by Joyce on Efua is 14 N.
