How many seconds would it take a boat to accelerate from 13 m/s to 26 m/s over a distance of 1.25 km?
1 answer:
Time taken by the boat to accelerate is 1 min 4 s.
<h3>How to calculate the time taken?</h3>V - V
= 2 a X ,
a = Vf2 - Vo2 / 2 X
= (26 m/s)2 -(13m/s)2 / 2(1250m)
= 507 m2/s2 / 2.5 m = 0.203 m/s2
Solve for time using the equation with acceleration known.
Vf = at + Vo ,
t = Vf - Vo / a = 26m/s -13m/s/ 0.203 m/s2
= 64 s
= 1 min 4 s
