Three objects are connected on a table as shown in Figure P4.73. The coefficient of kinetic friction between the block of mass m2 and the table is 0.350. The objects have masses of m1 = 4.00 kg, m2 = 1.00 kg, and m3 = 2.00 kg as shown, and the pulleys are frictionless. (a) Draw a diagram of the forces on each object. (b) Determine the acceleration of each object, including its direction. (c) Determine the tensions in the two cords. (d) If the tabletop were smooth, would the tensions increase, decrease, or remain the same? Explain. Figure P4.73

(a)

To determine
The forces on the masses.

Explanation

Given Info: The masses are m1=4.00kg , m2=1.00kg and m3=2

(b)

To determine
The acceleration of the masses.

(c)

To determine
The tension on the two cords.

(d)

To determine
The tension on the two cords.
