An arrow fired from a bow at a speed of 60 m / s. Determine the kinetic energy of an arrow if its mass is 200.
| April 27, 2021 | education
Task data: V (arrow speed at the time of the shot) = 60 m / s; m (boom mass) = 200 g (in SI m = 0.2 kg).
The kinetic energy of the arrow at the time of the shot can be calculated by the formula: Ek = m * V ^ 2/2.
Calculation: Ek = 0.2 * 60 ^ 2/2 = 360 J.
Answer: The arrow at the time of the bow shot had a kinetic energy of 360 J.
