Homework Statement
A river flows due north with a speed of 2.90 m/s. A man rows a boat and reaches the opposite shore right across its initial position; his velocity relative to the water is 5.50m/s. His landing point is due east relative to its initial location. The river is 1000 m wide.

I got it! You guys were trying to tell me that the time intervals should have been 2-1.5 and not 2-1. I thought because it said "use the info between t=1 and t=2 to solve the problem" that I had to use t=1 and t=2. But I just did 1.4-1/2-.15 and got 0.8 and that was correct :).
I think I got...
This is the figure with the problem. I don't think acceleration is constant in this problem? Do you think it's asking for the instantaneous acceleration, maybe?
No, it's online so it automatically assigns the units (that's why I don't usually pay attention to them). Because if I did the formula correctly wouldn't it be 0.4? When I get it wrong it says "Recall that the definition of average acceleration is the change in velocity divided by the change in...
My initial velocity is wrong? it's not 1? Wouldn't it be .5/.5=1? So then 1.4-1 within the acceleration equation. I guess I'm a bit confused what I'm doing wrong
Currently a senior at BU and taking Physics 105 (General Physics 1). Never took physics in high school so I'm sure I'll be on here a lot asking questions!
Homework Statement
A remote controlled toy car starts from rest and begins to accelerate in a straight line. The figure below represents "snapshots" of the car's position at equal 0.5 s time intervals. (Assume the positive direction is to the right. Indicate the direction with the sign of your...
