Q: Two masses M1 = 6.10 kg and M2 = 4.10 kg are on a frictionless surface, attached

Acceleration of the bodies = 17.1/6.1 = 2.8 m/s2 Now for m1 Fcos25.3 - 17.2 = 4.1*2.8 => F = 31.74N

Question

Two masses M1 = 6.10 kg and M2 = 4.10 kg are on a frictionless surface, attached by a thin string. The tension in the string connecting the two masses is 17.1 N. The force F pulls on M2 at an angle of 25.3° from the horizontal as shown in the figure. Calculate the magnitude of the force F.

Explanation / Answer

Acceleration of the bodies = 17.1/6.1 = 2.8 m/s2

Now for m1

Fcos25.3 - 17.2 = 4.1*2.8

=> F = 31.74N
