Hi,
we Know that,
Kinetic energy of an object which is moving with velocity v and having mass m [tex]Kinetic energy=mxv^2/2.........................(1)here m=70kg\\and v=10m/s\\Put values of m and v in equation 1\\kinetic energy= 70x10^2/2\\kinetic energy=35x100\\=3500joule[/tex]
therefore kinetic energy of bicycle and you=3500Joule
Hope this answer will help you
