friction make non moving objects starts to move
there are different types of force which may help them to move
The right answer is they both have kg in common
Answer:
7840 N
Explanation:
F = Nμ
F = mgμ
F = (2000 kg) (9.8 m/s²) (0.4)
F = 7840 N
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
