An object has a kinetic energy of 25 J and a mass of 34 kg, how fast is the object moving?
The formula for kinetic energy is:
KE = 1/2 * m * v^2
Where KE is kinetic energy, m is mass, and v is velocity/speed.
Rearranging the formula:
v^2 = (2 * KE) / m
Plugging in the given values:
v^2 = (2 * 25 J) / 34 kg
v^2 = 1.47 J/kg
Taking the square root to solve for v:
v = √(1.47 J/kg)
v ≈ 1.21 m/s
Therefore, the object is moving at approximately 1.21 m/s.
