KE =(1/2)mv^2
insert your numbers to find how much kinetic energy you have.
then double that number and solve for v
which gives you how fast the sled will have to go in order to reach that kinetic energy</span>

Answer:
zero
Explanation:
Work done = - 400 J
In an isothermal process, the temperature remains constant. So, according to the first law of thermodynamics
dQ = dU + dW
As the temperature remains constant and the change in internal energy is the function of change in temperature, here change is temperature is zero so the change in internal energy is also zero.
