The total displacement is equal to the total distance. For the east or E direction, the distance is determined using the equation:
d = vt = (22 m/s)(12 s) = 264 m
For the west or W direction, we use the equations: a = (v - v₀)/t d = v₀t + 0.5at²
Because the object slows down, the acceleration is negative. So, -1.2 m/s² = (0 m/s - 22 m/s)/t t = 18.33 seconds d = (22 m/s)(18.33 s) + 0.5(-1.2 m/s²)(18.33 s)² d = 201.67 m
Thus, Total Displacement = 264 m + 201.67 m = 465.67 or approximately 4.7×10² m.
The three branches of science are life, earth, and physical science. Life science deals with living organisms, so, biology is the most important of these sciences, although there are many. Earth science deals with Planet Earth, studying its atmosphere, lithosphere, etc. Physical science studies the inorganic world.
