Question
An object starts from rest at Position 1 on a track and slides to Position 3.
At Position 2, the total energy of the block is 230 J. At Position 3, the potential energy of the block is 50 J. From Position 2 to 3, 15 J of energy were lost due to
friction. From Position 1 to 2, 20 J of energy were lost due to friction. Solve for the total energy at Position 1 and the kinetic energy of the block at Position 3.
O A Position 1 Total Energy 230 J: Position 3 Kinetic Energy: 180 J
B Position 1 Total Energy: 265 J. Position 3 Kinetic Energy: 215 J
O C Position 1 Total Energy: 245 J. Postion 3 Kinetic Energy. 160 J
O D Position 1 Total Energy: 250 J; Position 3 Kinetic Energy: 165 J
