Hiya all, i'm stuck on a physics question set for homework. It asks "draw vector diagrams to scale to show the vertical and horizontal components of the velocity of the tip of the hand at quater-past, twenty past, twenty-five past and half past the hour." The hand is 20cm long so using the circumference formula and dividing it by time, i get 0.00034m/s as the velocity at quater past. I've drawn the hands and the x and y axis so is the x and y axis both 0.00034m/s or that x=0.00034m/s and y=om/s? or do i have to work out the velocity of the tip at those points and then work out the components? if so, how do i do that? thanx.
