Answer: It is the same amount of weight as the girl is putting on the pogo stick. When you are pushing something downward then gravity will push back with the equal amount of force.
Explanation:
Answer:
1/2 m v^2 + 1/2 I ω^2 = m g h conservation of energy
I = 2/5 m R^2 inertia of solid sphere
1/2 m v^2 + 1/5 m ω^2 R^2 = m g h
1/2 v^2 + 1/5 v^2 = g h
v^2 = 10 g h / 7 = 1.43 * 9.80 * 19 m^2/s^2 = 266 m^2/s^2
v = 16.3 m/s
v = R ω
ω = 16.3 / .6 = 27.2 / sec
The work done on the sail is 600 J
Explanation:
The work done to lift the sail is equal to the gain in gravitational potential energy of the sail, therefore is:
where
m is the mass of the sail
g is the acceleration of gravity
(mg) is the weight of the sail
is the change in height of the sail
In this problem we have
mg = 150 N (weight)
Substituting, we find the work done:

Mass and velocity are the two terms which affect momentum of a bicycle going hill down.
Explanation:
As we know that Momentum describes the motion of an object. It is the combination of the objects mass and velocity.
So, obviously with no doubt mass and velocity are the two terms which affect momentum.
Momentum(p) = Mass(m) * Velocity(v)
The momentum also depends upon the mass and speed of the object.
More the mass of the object more is the momentum.
Depending upon the gravity and bicycle's motion speed momentum varies.
Bicycle moves faster the down hill if it moves with some speed as it has lesser mass the momentum also will be less.
