(10 points) Masses m₁ = 2 kg and m₂ = 3 kg connected by a light string are placed on a horizontal surface with friction coefficient k = = 0.1. A force F = 9.8 N is applied to m₂. Find the acceleration of the system and the tension T in the string. T M₁ My 18 (10 points) A 0 5-kg block (m.) is released from rest at the top of a curve- 3. 11
