3) You are helping a patient to strengthen their hip flexors. Your patient is performing a hip flexion exercise as illustrated below (assume knee in full extension). While he was standing, you measured the distance from the hip joint to the center of mass of the thigh, shank and foot to be 0.32, 0.68, and 0.98m. The masses of his thigh, shank, and foot are 15.6, 11.2, and 3.1kg. Calculate the amount of hip flexor muscle torque required to hold the leg isometrically at 35⁰. Foot, 0.98m from Hip Shank, 0.68m from Hip Thigh, 0.32m from Hip Hip Joint

The forearm of length Larm=35.4 cm shown in the figure is positioned at an angle θ with respect to the upper arm, and a 5.30-kg ball is held in the hand. The total mass ?totalmtotal of the forearm and hand is 3.00 kg, and their center of mass is located at LCM=14.6 cm from the elbow. The biceps muscle attaches to the forearm at a distanceLbiceps=3.5 cm from the elbow. What is the magnitude of the force Fbiceps that the biceps muscle exerts on the forearm for ?=49∘? What is the magnitude of the force Fjoint that the forearm exerts on the elbow joint for ?=49∘?
A nucleus that captures a stray neutron must bring the neutronto a stop within the diameter of the nucleus by means of thestrong force. That force, which “glues” the nucleus together, is approximatelyzero outside the nucleus. Suppose that a stray neutronwith an initial speed of 1.4 * 107 m/s is just barely captured by anucleus with diameter d = 1.0 * 10-14 m. Assuming the strongforce on the neutron is constant, find the magnitude of that force.The neutron’s mass is 1.67 * 10-27 kg.
Two sprinters leave the starting gate at the same time at the beginning of a straight track. The masses of the two sprinters are 58.5 kg and 66.5 kg. A few seconds later, the first sprinter is ahead of the second by a distance 5.1 m. How far ahead of the second sprinter is the center of mass of these two sprinters, in meters? If the speeds of the sprinters are 4.9 m/s and 2.2 m/s, respectively, how fast, in meters per second, is the center of mass moving? What is the momentum of the center of mass, in kilogram meters per second? How is the momentum of the center of mass related to the total momentum of the sprinters?
When a catcher in a baseball game catches a fast ball, he does not hold his arms rigid, but relaxes them so that the mitt moves several inches while the ball is being caught. Why is this important?
