How to calculate initial kinetic energy

Web13 dec. 2024 · It's a notion rooted in the concepts of classical physics as elucidated by Sir Isaac Newton. The formula for the energy of motion is: KE=0.5\times m\times v^2 K E = 0.5×m ×v2. where KE is kinetic energy in joules, m is mass in kilograms and v is velocity in meters per second. 00:03 12:50. 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
