Hi, I'd be grateful if you can tell me how to convert metres per minute squared (acceleration) to feet per second squared (also acceleration) and vice versa. I just can't do it!!! Thanks

Divide by 3600 to change meters per minute squared into meters per second squared then Times by 3.3 since there are 3.3 feet in every meter

Thanks a LOT. Wow, you're quite fast at responding.

heyy am still stuck in vectors
i dont get it ???
so if i have a question like this how do i solve it?
pointA and B have coordinates (4, 1) and (2, -5), respectively. Find a vector equation for the line which passes through the point A, and which is perpendicular to the line AB.
really appreaciate ur help
thanks :)

gradient of line from A to B =change in y/change in x=(-5-1)/(2-4)=3 so gradient of perpendicular =-1/3
y=mx+c
y=-1/3x+c Put point A in to this equation.
1=(_1/3)4+c
so c=7/3 and y=-1/3x+7/3
