Answer:Kinetic energy of the girl and her bike is 5.544 kJ
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
If you need to convert km/s to m/s its 500000000000 J
if you dont then the answer is 5000 J
KE = 1/2 x mass (kg) x speed<span>²</span> (m/s)
