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
Answer:
Inference
Explanation:
He is guessing that the power is out due to the fact that the light isn't turning on. However, we don't know if the power is really out or not, it could just be a broken light.
