Answer #1

From Newtons second law, we know that

where, F is the force applied on the body

p is the momentum

for F = 0,

dp/dt = 0

implies that

p = constant

So, for a projectile with zero/no force, the momentum is not zero, rather it is constant

Answer the following T for True and F for False: __ A vector space must have an infinite number of vectors to be a vector space. __ The dimension of a vector space is the number of linearly independent vectors contained in the vector space. __ If a set of vectors is not linearly independent, the set is linearly dependent. __ Adding the zero vector to a set of linearly independent vectors makes them linearly dependent.

Answer true or false: The fact that the sum of our fitted residuals is zero, when we estimate a model with Ordinary Least Squares, depends on the model including an intercept. Answer true or false: Contrary to the statement above, the reason that the fitted residuals sum to zero is because of the statistical property that the expected value of an unobserved disturbance term (u) is zero; this means that the u's in our model sum to zero, so the...
