Bottom rail is called the "stuff" that holds a car window in place.
here we can say that since the hill is friction less So total energy is now conserved
we can use the energy conservation principle now

here we can say that initial KE is zero as the child and sled is at rest
and the final potential energy will also be zero as the child will reach the bottom
So here we can say




so final speed will be 12.8 m/s
Answer:
Rotational kinetic energy = 0.099 J
Translational kinetic energy = 200 J
The moment of inertia of a solid sphere is
.
Explanation:
Rotational kinetic energy is given by

where <em>I</em> is the moment of inertia and <em>ω</em> is the angular speed.
For a solid sphere,

where <em>m</em> is its mass and <em>r</em> is its radius.
From the question,
<em>ω</em> = 49 rad/s
<em>m</em> = 0.15 kg
<em>r</em> = 3.7 cm = 0.037 m


Translational kinetic energy is given by

where <em>v</em> is the linear speed.

The current is
(120v) / (the resistance of the stove in ohms) .
The unit of the current is Amperes.
