Physics
Aparticle is moving along the x-axis so that its position at any time t is greater than and equal to 0 is given by x(t)=2te^-t?
a) find v(t).
b) find a(t).
c) at t=0, is the particle slowing down or speeding up? explain.
d) at what time(s), if any, does the particle change directions? justify your answer.
any would be greatly appreciated! !
