To solve this problem it is necessary to apply the concepts related to the Moment. The momentum represents the product of the mass and velocity of an object, that is
[tex]p = mv[/tex]
where
m = mass
v = velocity
At the same time using Newtonian relations, we can consider the Moment's equivalence as a function of Force and time as
p = Ft
Where
F = Force
t = time
Matching the two expressions we get that
[tex]mv = Ft[/tex]
Re-arrange to find t,
[tex]t = \frac{mv}{F}[/tex]
Our values are given as
[tex]m = 72300kg[/tex]
[tex]F = 35N[/tex]
[tex]v = 60cm/s(\frac{1m}{100cm})\rightarrow v = 0.6m/s[/tex]
Replacing we have that the time is
[tex]t = \frac{mv}{F}[/tex]
[tex]t = \frac{(72300)(0.6)}{35}[/tex]
[tex]t = 1239.4s[/tex]
Therefore would be take 1239.4s
