Web1 answer The answer is: d) 981 J To calculate the potential energy, we need to know the height of point A. Since this information is not provided, we can assume that point A is at the same height as the starting point of the track. Therefore, the height (h) is zero. PE = m x g x h = 20 kg x 9.81 m/s² x 0 m = 0 J Web29 aug. 2015 · 0. Yes, so the method I did was to calculate the initial potential energy, as well as the kinetic energy, add them to get the mechanical energy. Then I would sub in this value in as kinetic energy alone, as before hitting the ground it would be all converted to kinetic energy. The angle does NOT make a difference in this particular question ...
