heyy. no i didnt compute them to get a total speed. i used deltaV/time and got acceleration. then i multiplied acceleration times mass to get the total force. and thanks for the advice, I am not sure ill do it right but ill give it a shot. words usually confuse me!
Homework Statement
A 322-kg boat is sailing 14.5° north of east at a speed of 1.84 m/s. Thirty seconds later, it is sailing 34.2° north of east at a speed of 4.40 m/s. During this time, three forces act on the boat: a 33.6-N force directed 14.5° north of east (due to an auxiliary engine), a...
