Answer

Explanation:

Step1: Analyze vertical forces

The normal force $F_N = 490$ N and the gravitational force $F_g=- 490$ N. The sum of vertical forces $F_{net - y}=F_N + F_g=490+( - 490)=0$ N.

Step2: Analyze horizontal forces

The frictional force $F_f=-245$ N and the applied - force $F_a = 735$ N. The sum of horizontal forces $F_{net - x}=F_a+F_f=735+( - 245)=490$ N.

Step3: Calculate net force

Since the net - force in the vertical direction is 0 N, the net force acting on Hector and the toboggan is equal to the net - force in the horizontal direction. So, $F_{net}=F_{net - x}=490$ N.

Answer:

490 N
