This is in relation to a homework question: But I don't need assistance on the question itself, but the concept behind it.
A mass of .4kg travels in the positive direction for 67m/s until a separate force is applied to M in the negative direction at 14m/s for .027 seconds. Impulse = 32.4 It then asks, "What is the average magnitude of the force?"
I'm more confused on the wording - as to what is it asking specifically? Why is the force being asked to be represented as a magnitude when it should have direction as well?
J = F Δt
F=J/Δt
F= -32.4N*s/.027s
F=-1200N
Yet the answer states 1200N. Impulse should be negative, since it's coming in from the negative direction, right?
What am I missing?
