Ya that's what i was figuring out. Anybody else could help?

I knew that N is Newtons. What i was saying was for F in F=ma, the F is net force which means it has to be subtracted with any other forces. In this case it has to be subtracted with the opposing force right? That is what i meant.

So can i substitute F on the second equation with the value of N given in the question. It says that it is an opposing force. So i have to do F-N = m(v-u)/t. Right? Then i will have 2 unknowns F and V. What now?

Ive subtituted all the values given in the formula. From then, i couldn't figure out the next step

Homework Statement A loaded barge has a mass of 1.5exponent6 kg and its traveling at 3 metres per second. If a tugboat applies an opposing force of 1.2exponent4 N for 10s What is it final velocity? How long does it take to stop Homework Equations F = ma F = m(v-u)/tThe Attempt at a Solution

Wh What about the length of 2nd force? The magnitude is yet to be calculated

How can i draw to scale if i don't know the 2nd force?

Ok this is my diagram. Then what?

I have no idea how to do it

An upward force of magnitude 30N is combined with a second force F which makes an angle of 10degree with the horizontal. The resultant makes an anglre of 40degree with the horizontal. a. Determine the magnitude of the second force b. Determine the magnitude of the resultant
