    A fully laded oil super-tanker moves at a constant speed of 12 m/s. It's engines produce a constant forward force of 16 000 N. What is the size of the friction force acting on the tanker?:confused:

    If you're expecting us to just give you the answer, you're in the wrong place.

    What have you done so far? Where are you getting stuck?

    Hint #1: At a constant speed, the acceleration of the tanker is zero. What does Newton's 2nd law tell you about this situation?

    You actually wrote the answer down.

    Not quite, you still have to make a connection between the available facts and the actual answer. You also have be familiar with the reference.

    I suspect we can give this one a rest, guys. It looks like another one-hit wonder that just wanted the answer posted and isn't interested in thinking about the problem in light of whatever hints we might give.
