Which graph best represents the object's velocity? A boat is motoring upstream against the flow at 5.0 m/s. List all that apply We can plot vectors in the coordinate plane by drawing a directed line segment from the origin to the point that corresponds to the vector's components: STT 4.8 a small car is pushing a larger truck that has a dead battery. How do the speeds v0, v1, and v2 (at times t0, t1, and t2) compare? What are the values of the velocity vector components v1,x and v1,y (both in m/s) as well as the acceleration vector components a1,x and a1,y (both in m/s2)? B The frequency will stay the same 1.
