The rockets accerlate at 1200m/s^2, Superman catches it 30m from home, and decelerates it with 2700N. Once he stops the rocket, he applies a 2700N force for 2m throwing it 10m to thrid base. If he is safe Flash immediately begins to give high fives at a rate of 1 for every thousandth of a second, how many does he get to before the ball arrives? if he is out he has to buy superman a $2.99 hero hotdog for every hundredth of a second he was beaten, how much does he spend? What is flash's fate?
