hey guys, im a lil confused with this one, not really with the concept, just how to start...(adsbygoogle = window.adsbygoogle || []).push({});

4) a snowmobile is being driven across a frozen lake. Vector V1 and Vector V2 in the diagram represents its velocity at two instants 3 s apart. 1 cm = 5 m/s

Determine [tex]\overrightarrow{\Delta V}[/tex] and the average acceleration.

i know i have to find the vector difference in v2 and v1 and the divide that by change in time but in the diagram all the teacher did was draw 2 lines (vectors) without an angle or a line showing where 180 degrees is, and just labeled them v1 and v2. how do i do the vector subtraction? i know i have to put them tail to tail, but how do i do it without knowing wat the angles are?
