1. The problem statement, all variables and given/known data

The acceleration of a particle is given by a=vx(cxr) where r is the position, v is the velocity and c is a constant.

Show that the following are constants

(a)|v|

(b)c.(rxv)

(c)c.v-1/2|cxr|^2

3. The attempt at a solution

a=c(v.r)-r(v.c)

d/dta=d/dt[c(v.r)-r(v.c)]
