Answer:
The bikers speed at the top of other hill is <u>25.82 m/s.</u>
Explanation:
Considering the biker is riding on a frictionless surface.
∴ There is no non-conservative or external force acting on the biker.
Hence we can conserve the energy of biker and bike as a system.
Let,
= 44m
= 10m
Since the biker starts from rest , his initial speed = 0 m/s
Let final speed of the bike at the top of other hill be .
∴ Initial Energy (at the top of 44m hill) =
Final Energy (at the top of 10m hill) = .
Conserving both the energies , we get
=
∴
Substituting the values for g , ,
, we get
= 25.82 m/s
