294000J
Explanation:
Given parameters:
Height of hill = 500m
Mass of Chris = 60kg
Unknown:
Potential energy increase = ?
Solution:
Potential energy is the energy by virtue of the position of a body.
Potential energy = mgh
m is the mass of the bike
g is the acceleration due to gravity
h is the height
At the base of the hill,
P.E = mgh = 60 x 9.8 x 0 = 0J
At the top:
P.E = mgh = 60 x 9.8 x 500 = 294000J
Potential energy increase = 294000J - 0J = 294000J

On that list of choices, 'C' is the only "example" of a plane.
None of the choices "describes" a plane.
Answer:
The answer to your question is a = 1.3 m/s²
Explanation:
Centripetal acceleration is the motion of a body that transverse a circular path.
Data
mass = 7 kg
radius = r = 1.3 m
angular rate = w = 1.0 rev/s
centripetal acceleration = a = ?
Formula
a = rw²
Substitution
a = (1.3)(1)²
Simplification and result
a = 1.3 m/s²
Answer is 12 milesBecause yeah
