How many meters is what? I don't have a distance. I was thinking inverse cos of 36 degrees. That would give me the hypotenuse right?

Homework Statement Bob heads out into a lake at an angle of 36 degrees, with respect to the shore. If his boat is capable of a speed of 1.7 m/s, how far from land will he be in 7 min and 23 s? Answer in units of m. Homework Equations I have no idea what equation would work for this...

ok, i tried it, solved for a and I got .030 m/s^2 = a. i typed that into my homework answers, and it said it was incorrect (we have multiple times to try it) and when I do v=at, 3.8=(.030)t, I get 125.3 seconds...seems a bit too much time. am i doing something wrong?

But then we have two variables, a, and v, how do I solve then? it doesn't work if you manipulate and substitute v =at because then the other variable, t, comes in.

Homework Statement A hockey puck sliding on a frozen lake comes to rest after 238 m. If its initial velocity is 3.8 m/s what is its acceleration if it is assumed constant? Answer in units of m/s^2 How long is it in motion? What is its speed after traveling 180 m? Homework Equations x=xo +...
