The mechanical energy of a bicycle at the top of a hill is 6,000 j. the bicycle stops at the bottom of the hill by applying the brakes. if the potential energy of the bicycle is 2,000 j at the bottom of the hill, how much thermal energy was produced?

Thermal energy produce =4,000 J.

Explanation:

Given that

Mechanical  energy at the top of hill = 6,000 J

Mechanical  energy at the bottom of hill = 2,000 J

We know that energy is conserve

Energy at top of hill = energy at bottom of hill + Thermal energy produce

So now by putting the values

Energy at top of hill = energy at bottom of hill + Thermal energy produce

6,000 = 2,000+ Thermal energy produce

Thermal energy produce =6,000-2,000 J

Thermal energy produce =4,000 J.

As we know that thermal energy produce due to friction when one mechanical component slides on the other mechanical component then always heat is generated and this heat is known as thermal energy.

i wanna say it’s between b and d, leaning more towards b.

as technology advances, new experiments often expose problems in accepted theories. c

hope i
