3. The diagram shows a 0.41 kg object sliding from A to B on a frictionless inclined plane. When the block reached Bit continues to move along a horizontal surface BC where a kinetic frictional force acts. As a result the block slows down coming to rest at C. The kinetic energy of the block at A is 37). a. What is the speed of the cart in point B?[3] b. How much energy is converted into heat during section BC? (3) c. Using energy principles calculate the stopping distance BC if = 0.05 on the diagram. [3] d. What would be the constant acceleration for the section BC(use energy principles)? (3) 20 N om - 70
