My bicycle has a mass of 10 kg. When I'm riding on it, and I speed up to a certain speed, the bike and I gain 5747.5 Joules of kinetic energy. When my cousin, who has a mass of 75 kg, rides my bike, and speeds up to half that speed, he and the bike gain 1285.625 Joules of kinetic energy. What is my mass?

From v to V
I have a mass of 80 kg. I sped up from v m/s to V m/s, and in the process, my kinetic energy increased by 10,000 Joules. If (V + v) is 75 m/s, what is the value of (V - v)?
