1. The problem statement, all variables and given/known data A 2175 kg test plane has an engine that can deliver a maximum power of 5.28×105 watts. The pilot hits the throttle when the plane is flying at 46.8 m/s and maintains maximum power for 6.5 seconds. What is the plane's initial kinetic energy? What is the plane's change in kinetic energy? What is the plane's final kinetic energy? What is the new speed of the plane after the 6.5 seconds? 3. The attempt at a solution I got the initial kinetic energy to be 1.5 x 10^6 J, but do not know how to get the other parts. Please help!
