WebDec 14, 2024 · If a mass that weighs 8 kg is held at a height of 10 m, what is its potential energy? (Answer: PE = (8 kg)*(9.8 m/s 2)*(10 m) = 784 kg*m 2 /s 2 = 784 J) Now consider an object with a kinetic energy of 800 J and a … WebPE = m g h = 2 kg × 9.8 m/s2 × 0.4 m = 7.84 kg m2 /s2 = 7.84 J Kinetic Energy The formula is: KE = ½ m v 2 Where m is the object's mass (kg) v is the object's speed (m/s) Example: What is the KE of a 1500 kg car going at suburban speed of 14 m/s (about 50 km/h or 30 mph)? KE = ½ m v 2 KE = ½ × 1500 kg × (14 m/s) 2 KE = 147,000 kg m 2 /s 2
