Simplify as much as b and c are three points in the plane. where a, 2. let u and v two non-parallel nozero vectors. determine the real number a so that the vectors au + (1- a)v and (2 + a)u + av are parallel.

Ke reqd to move from 0 to 50 will be proportional to 50x50 or 2500. this is equal to w.  to change vel from 50 to 150 you need energy prop to 22500 - 2500 = 20,000. this corresponds to 8w.  best answer is a) . work reqd is prop to velocity squared.
