A 0.40-kg cart with charge 4.0 x 10-5 C starts at rest on a horizontal frictionless surface 0.50 m from a fixed object with charge 2.0 x 10-4 C. When the cart is released, it moves away from the fixed object.

Which of the following is an example of Newton's first law of motion? Sam's bike hits a curb and he flies over the handlebars, onto the grass. A feather and a brick are dropped from a ladder. The brick exerts a greater force when it hits the ground.
