There is the information and then the questions: A stationary block has a charge of +6.0×10-4 C. A 0.80-kg cart with a charge of +4.0×10-4 C is initially at rand separated by 4.0 m from the block. The cart is released and moves along a frictionless surface to a distance of 10.0 m from the block.

1: Determine the electric potential energy of the initial state.

2: Determine the electric potential energy of the final state. Express your answer to two significant figures and include the appropriate units.

3: Determine the change in electric potential energy. Express your answer to two significant figures and include the appropriate units.

4: Determine the speed of the cart. Express your answer to two significant figures and include the appropriate units.
