Blocks A , B , and C are placed as in ? ig. P5.101? and connected by ropes of negligible mass. Both A and B weigh 25.0 N each, and the coefficient of kinetic friction between each block and the surface is 0.35. Block C descends with constant velocity. (a) Draw separate free-body diagrams showing the forces acting on A and on B. (b) Find the tension in the rope connecting blocks A and B. (c) What is the weight of block C? (d) If the rope connecting A and B were cut, what would be the acceleration of C?
Psychotherapy & Contemporary Psychodynamic Treatments Psychotherapy ● The treatment of disorders of the mind or personality by psychological methods ● A form of treatment for problems of an emotional nature in which a trained person deliberatively establishes a professional relationship with a patient in order to remove, modify or retard existing symptoms, to mediate disturbed patterns of behavior, and to promote positive personality growth and development ● How do we know it works ○ Consumer Reports Survey (1995) ■ 4000 people ■ Major findings ● Majority felt better ● MDs, PhDs, and CSWs all helped ● Effect of therapy = therapy + medication ● Longer treatment = more improvement ● Are all treatments effective ○ Most evidence suggests that all commonly used treatments have relatively equivalent levels of effectiveness ○ Psychodynamic ○ Client-centered ○ Gstalt ○ RET ○ CBT ○ Behavioral Interventions ● What you can change & what you can’t ○ Anxiety & Depression = Yes ○ Deeper issues =
