Chapter 17, Problem 30P

* A stationary block has a charge of $\text{+6}\text{.0 }\times {\text{ 10}}^{\text{-8}}\text{C}$. A 0.80-kg cart with a charge of $\text{+4}\text{.0 }\times {\text{ 10}}^{\text{-8}}\text{C}$ is initially at rest and separated from the block by 0.4 m. The cart is released and moves along a frictionless surface to a distance of 1.0 m from the block. Determine as many values of the physical quantities describing the motion of the cart as you can.
