The person is grasping the chain with both hands at a distance of 0.70 meters from their chest. The dock is supported by two wooden piles, and some water is visible beneath.**Additional Note:**To gain a deeper understanding of the physics or mechanics involved in this scenario, refer to the detailed explanation provided on Page 335.

Given data: Mass of crab trap (m) = 3.3 kg Distance (r) = 0.70 m Required: Torque (τ) We know that Acceleration due to gravity (g) = 9.8 m/s2 The gravitational force due to trap F = mg = (3.3 kg)(9.8 m/s2) = 32.34 N The representation of torque and force The angle (θ) = 90° The torque is given by τ = rFsinθ = (0.70 m)(32.34 m)(sin90°) = 22.638 N.m ≈ 23 N.m The torque exerted by the trap about the person's shoulder is 23 N.m

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
