Web20 feb. 2024 · Calculate the temperature from the heat transferred using Q = Mgh and ΔT = Q mc, where m is the mass of the brake material. Insert the values m = 100kg and c = 800J / kg ⋅oC to find ΔT = (7.35v × 106J) (100kg)(800J / kgoC) = 92oC. Discussion This temperature is close to the boiling point of water. WebThe net work is the change in kinetic energy of the object, which in this case would be zero because the velocity does not change (remember KE is 1/2mv^2). But the work that we have done on the object is not zero because we are referring only the force we exerted, not the net force. We could also ask how much work gravity did on the object, and ... WebBecause the calculation is for energy, which is not a vector quantity. I also tried to calculate in the vertical direction after reading this post. I was curious as to why the difference between the two answers. It's because the angle also shifts slightly from 45 degrees as the vertical velocity drops slightly. how much money did thankmas raise 2021
