IUPUI PHYS 15200 Page 1 of 2 Pre-Lab03: NEWTON’S LAWS Name Due at the beginning of the lab period Two blocks are connected by a massless string that passes over a massless pulley. The block of mass m 1 sits initially on a flat frictionless surface, while the block of mass m 2 hangs freely. When the system is released, the masses move at constant acceleration. 1. Suppose that mass m 1 starts from rest and slides a distance x in time t . Derive an expression for its acceleration using the equations for constant acceleration. Call this the “kinematical acceleration.” 2. Draw free-body diagrams for each block. 3. Derive an expression for the magnitude of the acceleration using Newton’s laws. Call this the

Let the coefficient of friction equal μ k . 5. Draw free-body diagrams for each block. 6. Derive an expression for the magnitude of the acceleration of the system using Newton’s laws given the presence of kinetic friction. 7.
