a body moves according to the following:
ay=2-4t
ax=-1
vy=2t-2t2
vx=1-t
x0=2
y0=3

what is the tangential acceleration when t=1?
what is the radius of curvature of the motion when t=1?

aT=[tex]\vec{a}[/tex]dot[tex]\vec{v}[/tex]/|v|
at t=1, [tex]\vec{v}[/tex]=0 so there is no tangential acceleration, how can this be true???

the secon part of the question is also not making sence

ar=v2/r, but here v=0 and ar=3 since there is no aT and ax=-1, ay=-2????
