The final speed of Vivian after 12.75 seconds is 2.485 m/s.

What is final velocity of object in motion?

The final Velocity of an object in motion is defined as the Velocity attained by a body after completing or reaching certain distance or a given or certain time interval.

a = Δv/Δt

a = (v - u) / (t₂ - t₁)

where;

  • u is the initial velocity of the object
  • v is the final velocity of the object
  • t₂ is the final time
  • t₁ is initial time of motion

0.06 = (v - 1.72) / (12.75)

12.75(0.06) = v - 1.72

0.765 = v - 1.72

v = 0.765 + 1.72

v = 2.485 m/s

Thus, the final speed of Vivian after 12.75 seconds is 2.485 m/s.
