A football is kicked from the ground with a velocity of 38m/s at an angle of 40 degrees and eventually lands at the same height.
Anastasy [175]

Initially, the velocity vector is \langle 38cos(40^{\circ}),38sin(40^{\circ}) \rangle=\langle 29.110, 24.426 \rangle. At the same height, the x-value of the vector will be the same, and the y-value will be opposite (assuming no air resistance). Assuming perfect reflection off the ground, the velocity vector is the same. After 0.2 seconds at 9.8 seconds, the y-value has decreased by 4.9(0.2)^2, so the velocity is \langle 29.110, 24.426-0.196 \rangle = \langle 29.110, 24.23 \rangle.

Converting back to direction and magnitude, we get \langle r,\theta \rangle=\langle \sqrt{29.11^2+24.23^2},tan^{-1}(\frac{29.11}{24.23}) \rangle = \langle 37.87,50.2^{\circ}\rangle

The theory of evolution is
tresset_1 [31]

one of several competing scientific models that all seem equally successful in explaining the nature of life on Earth

Explanation:

  • The theory of evolution is one of the several competing scientific models that all seems to successfully explain the nature of life on earth.
  • A theory is usually drawn from careful observation of scientific investigation.
  • Theories generally provides explanation into a phenomenon that occurs in nature.
  • They are products of careful scientific observations and experiments.
  • The theory of evolution is but one of them.
