A 30.7 kg girl and a 59.8 kg boy are on the surface of a frozen lake, 10.5 m apart. Using a rope, the girl exerts a horizontal 4.20 N force on the boy, pulling him toward her. Calculate the magnitude of the girl's acceleration.

Two blocks of masses M1 = 3.5 kg and M2 = 5.7 kg are at rest on a horizontal surface with a coefficient of friction uk = 0.12. You start them moving by pushing on block 1 with a force F1H = 33 N at an angle of 42 degrees below the horizontal. The magnitude of kinetic friction force on each bock is f1 = 6.76 N and f2 = 6.70 N Determine the acceleration of the blocks and the magnitude of the normal force between the blocks.
