Question

1. A sled is being pulled to the left by 5 dogs, each dog pulling with 6 Newtons of force. Find the net force (ignore friction).

2. If a person pulls on a cart to the right with a force of 10N and a second person pulls to the left with a force of 3N, what is the net force on the cart ignoring all other forces?

3. A 2N and 6N force pulls on an object to the right and a 4N force pulls to the left a 0.5kg object. What is the net force on the object if you ignore all other forces?

4. A 20kg bike accelerates at 10m/s^2. With what force was the person pedaling if friction exerted a force of 100N

5. If a person is pushing a cart with a force of +40N, friction is -10N and the cart accelerates at 0.5m/s^2, what is the mass of the cart?
