A bowling ball with a mass of 6 kg is given two hundred joules of kinetic energy when roll down the lane. It looses 5 joules of kinetic energy due to friction on the lane. It transfers 150 joules of kinetic energy to the pins. Collisions with the pin causes 5 joules of its kinetic energy to be converted to thermal energy. What is the velocity of the bowling ball after it rolls through the pin in meters per second? ​

Follow these directions and answer the questions. 1. set up the ripple tank as in previous investigations. 2. bend the rubber tube to form a "concave mirror" and place in the ripple tank. the water level must be below the top of the hose. 3. generate a few straight pulses with the dowel and observe the reflected waves. do the waves focus (come together) upon reflection? can you locate the place where the waves meet? 4. touch the water surface where the waves converged. what happens to the reflected wave? 5. move your finger twice that distance from the hose (2f = c of c, center of the curvature) and touch the water again. does the image (the reflected wave) appear in the same location (c of c)? you may have to experiment before you find the exact location. sometimes it is hard to visualize with the ripple tank because the waves move so quickly. likewise, it is impossible to "see" light waves because they have such small wavelengths and move at the speed of light. however, both are examples of transverse waves and behave in the same way when a parallel wave fronts hit a curved surface.
