Practice question

Given: A 2 kg object moves with a velocity of 4 m/s along the x-axis. What is the velocity of its nter of mass? These values define the system as per NCERT data. Formula: Given: v = 4 m/s along x-axis. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: For a single object, the velocity of the nter of mass equals the velocity of the object. . Velocity of CM = 4 i m/s . Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
