A block and sphere are connected by a cord that passes over a pulley as shown. Neglect friction and assume the cord is massless. Take m = 2.00 kg, m = 7.45 kg, and 8 = 50.0. m m2 (a) What are the magnitude of acceleration (in m/s) of the block and sphere? 4.88 Write Newton's second law for each object. What forces act on each object? How are the tension forces that act on each object related? How are the accelerations related? m/s (b) What is the tension (in N) in the cord? (Enter the magnitude.) 19.6 Use one of your second-law equations and the result from part (a) to solve for T. N (c) What is the speed (in m/s) of each object 2.50 s after being released from rest? 12.2 It seems as if you have calculated the distance the system has moved. Use v = v; +at+v;= at and the result from part (a) to find v.. m/s (d) What If? If the incline under m is rough, what is the minimum value of the coefficient of static friction s for which the system will not move? 0.77
