Provide an appropriate response.Show that if a particle's velocity vector is always orthogonal to its acceleration vector then the particle's speed is constant.
What will be an ideal response?
Given: v and a are orthogonal. Thus v?a = v?(dv/dt) = 
d(v?v)/dt = 0.
So, v?v = 
2 = constant and thus 
= constant.
