I have a worksheet I recieved for make-up since I was absent. It is really hard since I miss the lesson. All the problems are similar, but I do no know where to start. Here is a sample problem. Will someone show me steps on how to do it?(adsbygoogle = window.adsbygoogle || []).push({});

A boat moves through the water with two forces acting on it. One is a 2.1 103 N forward push by the motor, and the other is a 1.9 103 N resistive force due to the water.

(a) What is the acceleration of the 1200 kg boat?

m/s2

(b) If it starts from rest, how far will it move in 10 s?

m

(c) What will its velocity be at the end of this time interval?

m/s
