A boat moves through the water with two forces acting on it. One is a 2000 N motor, and the o ther is an 1800 N restive force to the water. 1) What is the accelration of the 1000 kg boat?(adsbygoogle = window.adsbygoogle || []).push({});

Did I do this right?

a) (2000 cos 90 + 1800 cos 270 ) i + (2000 sin 90 + 1800 sin 270)j = 3800j N

sqrt(3800^2+0^2)= 3800 N.

a= 3800/1000 = 3.8 m/s^2
