Answer:
v = 10 m/s
Explanation:
Given: An object has a kinetic energy of 250 J and a mass of 5 kg
To find: Its velocity
Formula: [tex]KE = \frac{1}{2} mv^2[/tex]
Solution: In classical mechanics, kinetic energy (KE) is equal to half of an object's mass ([tex]\frac{1}{2}[/tex] × m) multiplied by the velocity squared. In this case, an object with a mass of 5 kg (m = 5 kg) is moving at a velocity of 10 meters per second (v = 10 m/s), the kinetic energy is equal to 250 Joules, or ([tex]\frac{1}{2}[/tex] × 5 kg) × 10 m/s².
Therefore, the velocity is v = 10 meters per second.
