use kinematic equations and newton's laws

7. Two blocks are connected on either side of a frictionless ramp. Determine the acceleration of the system and the tension in the string. 3.50 kg 8.00 kg 35.00 35.0 8. Mary pulls her 20kg suitcase at constant speed with a 35N force. The friction force between the ground and wheels of the suitcase is 20N. What is the coefficient of kinetic friction between these two surfaces
