Baby Kellyn was bouncing up and down in a "bouncy chair" which hangs from a chain that is attached to a spring. At oneparticular time, after jumping in the air, Kellyn and the chair were moving downward with a speed of 1.7 m/s while speedingup at a rate of 3.3 m/s?. Kellyn has a mass of 4.8 kg and the chair has a mass of 1.2 kg. Calculate the force (in units ofnewtons) that the chain exerted on the chair at this time. Consider a positive force to point up and a negative force to pointdown. The sign, positive or negative, of your answer is important. Later that day, Baby Kris was bouncing in a similar chair. Kris had a mass of 5.8 kg and this chair had a mass of 1.5 kg. At oneparticular time, after jumping in the air, Kris and the chair were moving downward with a speed of 1.8 m/s while slowingdown at a rate of 4.8 m/s?. Calculate the force (in units of newtons) that the chain exerted on the chair at this time.Consider a positive force to point up and a negative force to point down. The sign, positive or negative, of your answer isimportant.

a horse pulled a wagon with a force of 710 N and accelerated it at a rate of 0.47 m/s^2. If the wagon has a mass of 820 kg how much force (from friction, mud etc) is working against the horse to slow the wagon down?
To keep the calculations fairly simple, but still reasonable, we shall model a human leg that is 92.0 cm long (measured from the hip joint) by assuming that the upper leg and the lower leg (which includes the foot) have equal lengths and that each of them is uniform. For a 70.0 kg person, the mass of the upper leg is 8.60 kg, while that of the lower leg (including the foot) is 5.25 kg. Find the location of the center of mass of this leg, relative to the hip joint, if it is (a) fully extended, and (b) bent at the knee to form a right angle with the upper leg.
