Triceps muscle 4.0 cm Biceps muscle m₁ = 2.5 kg - 16 cm CG -X W 38 cm M (positive) "counter-clockwise" PHYSICS Determine the force generated by the biceps in order to maintain the forearm in this static position (zero movement). mo is the mass of the book. ma is the mass of the forearm/wrist/hand segment. The appropriate moment arms are indicated. +y m, = 4.0 kg CG Wo M (negative) "clockwise" +X

A yoyo of radius R and mass M is released from rest with the string vertical and its top end fixed up a support as shown below. How fast is the center of mass of the yoyo moving when it has fallen a distance of 47 cm. Ignore the mass of the string and express your answer if m/s

Problem 3 A log rolling downhill has an initial velocity of 0.5 m/s. The log is 2.0 m in length and 0.3 m diameter. It is of uniform density and has mass of 25 kg. If the log rolls without slipping, find the velocity when it has traveled a distance of 5.0 m down the slope of 30 degree pitch. -50 30° 0.5M/S
