Unformatted text preview: A 7 kg bowling ball starts down the lane at 5.5 m/s. By the time it reaches the end of the 19.16 m lane, it has slowed down to 4.7 m/s. How much work has been done by friction? What is the average force of friction between the lane and the ball? A 7 kg bowling ball hits the pins at a speed of 4.7 m/s. After colliding with the pins, the ball is now traveling at 1.8 m/s. How much energy did the ball transfer to the pins? Conservation of Energy problem set Out What are you going to study for the quiz tomorrow?...
