How to find the rate of acceleration?
It depends on what data you have. See below.
You probably were given a set of 4 formulas of motion. The three that include acceleration are
#v = u + a*t# #d = u*t + 1/2*a*t^2# #v^2 = u^2 + 2*a*d#
Newton's 2nd Law is another formula which involves acceleration. In formula form (Newton described it in words) it is
To use this set of formulas to find acceleration, choose the formula that has a place for the data you have. Plug the data into the appropriate places and solve for
