6. Drawing Free Body Diagrams: Draw the FBDS and label all forces for the objects described in the following scenarios. (6C) a) Two steel balls (A-top ball and B-bottom ball) are resting in a cylinder as shown below. Draw FBDs for both steel balls. b b) Draw the FBD for the stationary block shown in the image below. m 7. A 3.00 kg block of wood starting from rest slides down a 2.80 m wooden ramp that is inclined to an angle of 40 degrees. Because of a constant force of kinetic friction of 12.4 N acting on the block the entire descent, some of the block's initial energy is transformed into thermal energy. Explain how you could solve this problem to determine the speed of the block at the bottom of the ramp as well as the coefficient of kinetic friction between the ramp and the block. You are not required to show any calculations for this problem-just explain how the problem could be solved using words and/or diagrams. (6C) 8. A 1.0 kg wooden block is placed 80.0 cm from the centre of a record player (i.e. rotating platform). The record player is rotating at a uniform speed making a certain number of revolutions per minute. Using your knowledge of forces and Newton's Laws, describe the forces involved in making the block move in circular motion and explain what would happen if the record player started rotating faster. No calculations are required. (6A)
