Answer:
d = 5.10 m
Explanation:
As we know that here on the plane of the inclined there is no frictional force
So in these cases we can say that total mechanical energy will always remains conserved
so here we can say that
spring potential energy = gravitational potential energy of the block
as we know from the formula
now plug in the values in it
now as we know that the angle of inclination is 60 degree and height raised is 4.42 m
so here maximum distance moved along the inclined plane will be

Explanation:
Experts describes the rate of fossil fuel use as unsustainable because fossil fuel is a non-renewable source of energy. Fossil fuels are usually formed by a series of biology, chemical and geological activities acting in nature. They take several millions of years to form and accumulate in nature.
- Most of the internal combustion engines in automobiles, factories e.t.c relies on fossil fuels.
- With the heavy demand, reserves are be depleted.
- The rate of formation of new sources is very slow and may not suffice in our life time.
- Therefore, we cannot continue to use this source of energy that cannot be adequately sustained.
