You have a velocity function of v(t) = 8t. The starting position of the object described by this function is
zero. Which equations also describe the motion of
this object? *

r(t) = (4t^2) + 2
=
a(t) = 4t^2
r(t) = 4t^2
a(t) = 8
v(t) = 8

Dry ice is solid carbon dioxide that is used in the transport of food and medicine. dry ice becomes a gas at –78.5°c without becoming a liquid first.

Taylor's experiment: 1. accurately measured the speed of light 2. locked together the phases of two light sources so that the interference pattern would not shift 3. showed that man's reaction time was much slower than the speed of light 4. showed that individual photons have wave characteristics

What is the speed of an object at a given moment?
