so t = (v/2 + v)(1/a). and a = the 1st integral of v. and v= (frictional force/70) (is that right) but how do we get units in? and then frictinal force is the x component of the forces... but is there an f app?

i think we use vfinal = v initial + at. as v/2= v + at. and a = (sum of forces divided by mass). i also think I am in your class.

do you think there is an f app? or just friction force moving the boat. like a car on a road? i think it would be the same situation, do you?

what did you get for the sum of your forces
