A 150-g glider moves at v1 = 2.30 m/s on an air track toward an originally stationary 200-g glider as shown in Figure P16.53.

A student suggests roughly half the decrease in mechanical energy of the two-glider system is transferred to the environment by sound. Is this suggestion reasonable? To evaluate the idea, find the implied sound level at a position 0.800 m from the gliders. If the students idea is unreasonable, suggest a better idea. Figure P16 53arrow_forward
