Answer to Question #291539 in Physics for Peter

Question

A ship with a mass of 52 000 metric tons is capable of producing a thrust force of 25 800 kN while a total resistive force of 5 000 kN is against it, what is the acceleration of the ship? *

Answer 1

Given:

$m=52\:000\:000\:\rm kg$

$F_{\rm thrust}=25\:800\:000\:\rm N$

$F_{\rm resistive}=5\:000\:000\:\rm N$

The Newton's second law says

$$a=\frac{F_{\rm net}}{m}=\frac{F_{\rm thrust}-F_{\rm resistive}}{m}$$

$$a=\frac{25800000-5000000}{52000000}=0.4\:\rm m/s^2$$
