Answer:Kinetic energy of the girl and her bike is 5.544 kJ

Step-by-step explanation:

Given that a girl is riding bike at speed of 12m/s

Also, mass of Girl is 55kg and mass of bike is 22kg

Let, Total mass of girl and bike be M=22+55=77kg

Now, Kinetic energy is given by K=

Hence, Kinetic energy of the girl and her bike will be

K=

K=

K=5544J

Thus, Kinetic energy of the girl and her bike is 5.544 kJ
