Question

A 40 kg sled is pulled rightward across the ground by an applied force of 340 N. A friction force of 200 N acts in the opposite direction. Air resistance can be ignored.

a) What is the net force on the sled?

A) 140 N
B) 240 N
C) 340 N
D) 540 N

Answer 1

The net force on the sled is found by subtracting the friction force from the applied force, resulting in a net force of 140 N to the right.

Step-by-step explanation:

The net force on the sled is calculated by subtracting the frictional force from the applied force. Since the sled is pulled with an applied force of 340 N to the right and a frictional force of 200 N acts against it to the left, the net force is 340 N - 200 N which equals 140 N to the right. Therefore, the correct option is A) 140 N.
