If you start skating down this hill, your potential energy will be converted to kinetic energy. At the bottom of the hill, your
baherus [9]
Your potential energy at the top of the hill was (mass) x (gravity) x (height) .

Your kinetic energy at the bottom of the hill is (1/2) x (mass) x (speed)² .

If there was no loss of energy on the way down, then your kinetic energy
at the bottom will be equal to your potential energy at the top.

(1/2) x (mass) x (speed)² = (mass) x (gravity) x (height)

Divide each side by 'mass' :

(1/2) x (speed)² = (gravity) x (height) . . . The answer we get
will be the same for every skater, fat or skinny, heavy or light.
The skater's mass doesn't appear in the equation any more.

Multiply each side by 2 :

(speed)² = 2 x (gravity) x (height)

Take the square root of each side:

<u>Speed at the bottom = square root of(2 x gravity x height of the hill)</u>

We could go one step further, since we know the acceleration of gravity on Earth:

Speed at the bottom = 4.43 x square root of (height of the hill)

This is interesting, because it says that a hill twice as high won't give you
twice the speed at the bottom.  The final speed is only proportional to the
<em>square root </em>of the height, so in order to double your speed, you need to
find a hill that's <em>4 times</em> as high.

A square boat made from iron has overall dimensions of 2.00 cm x 11.0 cm x 11.0 cm. It has a mass of 213 g. What is its density?
kupik [55]

<u>Answer:</u> The density of boat is 0.88g/cm^3

<u>Explanation:</u>

To calculate the volume of boat, we use the equation:

V=lbh

where,

V = volume of boat

l = length of boat = 2.00 cm

b = breadth of boat = 11.0 cm

h = height of boat = 11.0 cm

Putting values in above equation, we get:

V=2.00\times 11.0\times 11.0=242cm^3

  • To calculate density of a substance, we use the equation:

\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}

We are given:

Mass of boat = 213 g

Volume of boat = 242cm^3

Putting values in above equation, we get:

\text{Density of boat}=\frac{213g}{242cm^3}\\\\\text{Density of boat}=0.88g/cm^3

Hence, the density of boat is 0.88g/cm^3
