Your initial speed is 12 m/s and your final speed is 13 m/s. If this change of speed took place over a distance of 156 m how long did it take.

The answer to your question is: 12.48 s

Explanation:

dа ta:

initial speed (is) = 12 m/s

final speed (fs) = 13 m/s

distance (d) = 156 m

time (t) = ?

Formula

d = ((fs + is)) / 2 t we clear time from this equation t = 2d / (fs + is)

Substitution t = 2 (156) / (13 + 12)

Process t = 312 / 25

t = 12.48 s
