A child is running at her maximum speed of 4m/s to catch an ice cream truck, which is stopped at the side of the road. When the child is 20m from the truck, the ice cream truck starts to accelerate away at a rate of 1.0m/s^2. Does the child catch the truck? I know to begin, you must create an equation of both the child and the truck, but I'm having great dificulty doing so. The teacher didn't give us any form of equations so we have to come up with them on our own. Please help!
