1. The problem statement, all variables and given/known data A 10.89kg bowling ball moves at 3.46 m/s. How fast must a 40.3g golf ball move so that the two balls have the same kinetic energy? 2. Relevant equations Kinetic Energy = (1/2)V^2 3. The attempt at a solution I set plugged the information into the kinetic energy problem and set them equal to each other to solve for V. (1/2)(10.89kg)(3.46m/s)^2=(1/2)(.0403kg)(V^2) V=238.3 m/s Thats not the answer in the back of the book though, I'm not sure what I'm doing wrong.
