Newton's first law of motion predicts the action of objects for which all existing forces are balanced. The first law, also referred to as the law of inertia, states that if the forces acting upon an object are balanced, the acceleration of that object will be 0 m/s/s. Objects at equilibrium will not accelerate. According to the law, an object will only accelerate if there is an unbalanced force acting upon it. The presence of an unbalanced force will change its speed, its direction, or both its speed and direction. All forces retaining to this law are related to inbalance

Given the question :
A small toddler is playing in his yard. Over the course of 29.01 s, he walks 2.099 m S before turning N and walking 1.429 m. What is his average velocity?
Distance walked south = 2.099 metre
Time taken = 29.01s
Distance walked north = 1.429 metre
Average Velocity = Displacement / time
The Displacement is hence,
(2.099 m - 1.429m) = 0.67m
Average Velocity = 0.67m / 29.01s
Average Velocity = 0.02309 m/s
Average Velocity = 0.0231 m/s
This is a big looking question for school and for 5 points.It seems to relate to superfluidity in helium III and helium IV and something called the "lambda" point. Though I can't do it justice yet and here, it looks as though i can find tis in "Heat and Thermodynamics", Mark W Zemansky ...If rho is the density of helium II, rhon the density of the normal part, and rhoz the density of the superfluid part rho=rhon+rhoz.At the lambda point, all the atoms are normal and rhon/rho = 1, whereas at absolute zero all the atoms are superfluid and rhon/rho=0.Best I can do with the info and point available ..ps, I think that both Bose and Einstein were nobel prize winners, and the word "Boson" is in honour of the, I believe, Indian physicist Bose. It is a very interesting question, and I can in no way do it justice here.
5.38
21 divided by 3.9 is 5.38 and the equation for acceleration is change in velocity divided by time
