A ball weighing 200 g is thrown at a speed of 8 8 m / s. Determine the kinetic energy of the ball at the moment of throwing.
| December 16, 2020 | education
Kinetic energy (Eк) is found:
Eк = mv ^ 2/2
Convert grams to kilograms
200 g = 0.2 (kg)
Now we just substitute the values and find the kinetic energy
Eк = 0.2 * 8 ^ 2/2 = 0.2 * 64/2 = 6.4 (J)
Answer: Eк = 6.4 (J)
