The situation given above can be answered through the concept of the First Law of thermodynamics which states that the change in internal energy is equal to the difference between the work done and the heat added to the system. The work done by the object is negative and the heat added is positive.
change in internal energy = -500J + 1400 J = 900 J

Answer:
ball D will fall toward the ground at the same time as ball C
Explanation:
both balls experience the same downward (vertical) force of gravity as such they will both fall down at the same time, given that all other factors are equal.
although the ball were through with different forces,
those forces where in the horizontal direction but the force of gravity (downward force) will act on them equally to bring them down at the same time
Hello!
A 1350 kg car travels at 12 m/s. What is it's kinetic energy ?
We have the following data:
m (mass) = 1350 kg
v (velocity) = 12 m/s
KE (kinetic Energy) = ? (in Joule)
Formula to calculate kinetic energy:
Solving:
