In nonuniform circular motion, the linear acceleration `vec a`, the angular acceleration, `vec alpha`, the angular velocity `vec v` the radius vector `vec r` and the angular velocity `vec omega` at any instant are related by the vector equation,

Options

A. `vec a = vec alpha xx vec r+ vec omega xx vec v`
B. `vec a = vec r xx vec alpha+ vec v xx vec omega `
C. `vec a = vec alpha xxr+ vec v xx vec omega`
D. `vec a = vec alpha xx r -vec omega xx vec v`

Answer

A
