1. Because, velocity vector (vector_v) = magnitude (vector_v) * unit_vector_v

Hence, acceleration can be due to change in direction as well as due to change in magnitude of velocity vector.

As both are constant, therefore acceleration (a) = 0

Because, Force (F) = mass (m) * a
If a = 0, => F =0
Hence, force required to keep the ball moving in a constant direction with constant velocity magnitude = 0 --Answer

2.
A. A rocket in space is able to propel itself in a specific direction at a specific velocity -- Newton's 1st Law (Law of Inertia) -- In absence of net external forces (resultant force = 0), remains in original state.

B. if the sun were vaporized, the earth would continue in a straight liner path indefinitely -- Newton's 1st Law (Law of Inertia) -- In absence of net external forces, remains in original state. -- Whatever were ...

  • " In question 2, you incorrectly add in the $3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "
