Question 2
When the problem states that a cart is moving along a road at a constant velocity. What does this mean about the forces acting on the cart?(1 point)
Responses

Constant velocity and force have no relationship.
Constant velocity and force have no relationship.

All the forces acting on the cart equal zero net force.
All the forces acting on the cart equal zero net force.

There are no forces acting on the cart.
There are no forces acting on the cart.

Constant velocity increases net force.

Answer 1

For Question 1, the best choice for increasing the net force on the cart is:

**Applying a braking force by dragging your foot.**

This is because applying a braking force introduces an unbalanced force on the cart, which alters its state of motion, potentially increasing the net force acting on it.

For Question 2, the correct response is:

**All the forces acting on the cart equal zero net force.**

This is because a cart moving at constant velocity indicates that the net force acting on the cart is zero, meaning that all the forces are balanced.
