In the pulley arrangement shown, a 5.0 kg racoon (an animal sometime called a 'trash panda' because it is often found eating food in garbage cans) is hanging on a 1.0 kg log over the side of a table. They are attached to a cart of unknown mass, m. The racoon and the log are attached together (i. e. you consider them as though they are one object). The coefficient of friction between the cart and the table is 0.30. If the acceleration of the mass and cart is 2.0 ms2 . a) Find the force of friction on the cart n terms of 'm' (m will be in your answer)

b) Solve for the cart's mass 'm'

c) Find the magnitude of tension in the string
