To calculate the mass of an object when its velocity is known, you need to have additional information such as the object's momentum or kinetic energy. Depending on the context and the available data, you can use different formulas.
If you know the object's momentum (p) and velocity (v), you can use the equation: Momentum (p) = mass (m) × velocity (v) Rearranging the equation, you can solve for mass (m): Mass (m) = Momentum (p) / Velocity (v)
If you know the object's kinetic energy (KE) and velocity (v), you can use the equation: Kinetic Energy (KE) = (1/2) × mass (m) × velocity^2 (v^2) Rearranging the equation, you can solve for mass (m): Mass (m) = (2 × Kinetic Energy (KE)) / velocity^2 (v^2)
It's important to note that without additional information, such as momentum or kinetic energy, you cannot determine the mass of an object solely based on its velocity.
