A 2.3-kg object is tossed upward from a point 24 m above the Earth's surface. At what height above the Earth (in m) will the gravitational potential energy of the Earth-object system have increased by 411 J

Height when the gravitational potential energy of the Earth-object system have increased by 411 J is 41.86 J

Explanation:

Given that,

Mass of the object, m = 2.3 kg

It is tossed upward from a point 24 m above the Earth's surface.

We need to find the height above the Earth (in m) will the gravitational potential energy of the Earth-object system have increased by 411 J.

Initially, the potential energy will be :

Final potential energy will be :

E= 552 + 411 = 963 J

Now,

So, height when the gravitational potential energy of the Earth-object system have increased by 411 J is 41.86 J

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

thermal energy is the answer
