A particle moving in the xy-plane has velocity vo=voxi^ +voyj^ at t=0. It undergoes acceleration a=bti^ -cvyj^, where b and c are constants. Find an expression for the particle's velocity at a later time t.

How can you improve the percent yield of copper in this lab? check all possible strategies that will you do so. measure reactants precisely. stir to the reaction take place. chill the reactants before combining them. wait patiently until the reaction completes. make sure to recover as much copper as possible.
