I need help with it

An aluminum block of mass m1 = 4.70 kg and a copper block of mass m2 = 7.40 kg are connected by a light string over a frictionless pulley. They sit on a steel surface as shown in the figure below, where theta = 38.0 degree . (See the table below for the appropriate coefficients of friction). When they are released from rest, will they start to move? Yes No If the blocks move, determine the magnitude of their acceleration. (If the blocks do not move, enter 0.) m/s2 If the blocks move, determine the magnitude of the tension in the string. (If the blocks do not move, enter 0.) N If the blocks do not move, determine the sum of the magnitudes of the forces of friction acting on the blocks. (If the blocks move, enter 0.) N Note: All values are approximate. In some cases, the coefficient of friction can exceed 1.0.

Explanation / Answer

A) no does not move

B)0

C)0

d) The force due to friction is = to the normal force of m2

N=m2gsin(x)
