The equation for Kinetic energy is KE = 1/2(m)(v)2 where m is mass and v is velocity. This problem states that you are looking for the kinetic energy (KE) of a bicycle with mass 25 kg traveling at 10 m/s. So m = 25 kg and v = 10 m/s.
When we plug these values into the KE equation, we get
KE = 1/2(25 kg)(10 m/s)2
= 1/2(25 kg)(100 m2/s2)
= 1250 kg*m2/s2
= 1250 Joules
Hope this helps. Let me know if you need any further clarification.
