To calculate the kinetic energy (K.E.) of a disc rolling on the ground, we need to consider both its translational and rotational kinetic energy. Here’s a step-by-step solution: ### Step 1: Identify the given values - Mass of the disc (m) = 5 kg - Radius of the disc (r) = 50 cm = 0.5 m (convert to meters) - Linear velocity of the center of mass (V_cm) = 10 m/s ### Step 2: Calculate the moment of inertia (I) of the disc ...
