Halliday, Resnick & Walker β Motion in Two and Three Dimensions: Problem 14
14 A proton initially has \(\vec{v} = 4.0\hat{i} - 2.0\hat{j} + 3.0\hat{k}\) and then 4.0 s later has \(\vec{v} = -2.0\hat{i} - 2.0\hat{j} + 5.0\hat{k}\) (in meters per second). For that 4.0 s, what are (a) the proton's average acceleration \(\vec{a}_{avg}\) in unit-vector notation, (b) the magnitude of \(\vec{a}_{avg}\), and (c) the angle between \(\vec{a}_{avg}\) and the positive direction of the \(x\) axis?
