2. A child’s toy consists of a truck that is mounted on a spring and moves horizontally on a surface. The truck has a mass of 50 g and the spring constant is 1.25 N/m. Assume the drag force is linear. (a) What is the natural frequency of the toy (include units)? (b) Draw a free body diagram for the truck and write down the equations of motion. (c) If the drag coefficient, b, is 0.6 kg/s, is the system not damped, underdamped, overdamped, or critically damped? Explain how you know.

A child’s toy consists of a m = 36 g monkey suspended from a spring of negligible mass and spring constant k. When the toy monkey is first hung on the spring and the system reaches equilibrium, the spring has stretched a distance of x = 17.7 cm, as shown in the diagram. This toy is so adorable you pull the monkey down an additional d = 4.6 cm from equilibrium and release it from rest, and smile with delight...
