Question

A m1 = 3.70 kg block on a smooth tabletop is attached by a string to a hanging block of mass m2 = 2.90 kg, as shown in Figure 6-34. The blocks are released from rest and allowed to move freely. Figure 6-34 (a) Is the tension in the string greater than, less than, or equal to the weight of the hanging mass? The tension in the string is less than the weight of the hanging mass. The tension in the string is equal to the weight of the hanging mass. The tension in the string is greater than the weight of the hanging mass. (b) Find the acceleration of the blocks. m/s2 (c) Find the tension in the string. N

Explanation / Answer

a) The tension in the string is less than the weight of the hanging mass. as there is accleration and net force is downward. b) 2.3*9.8-T=2.3*a T=4.1*a a=3.52 T=14.44
