the velocity, vm/s, of a particle moving in a straight line, at time t seconds is given by
v=1+9/t^2
for 1 is less than or equal to t which is less than or equal to 3. when t=3, the particle is 6m from a fixed point o
on the line.

find the acceleration when t=2
find an expression in terms of t for its distance from the fixed point.
find the distance travelled between t = 1 and 1 = 3.

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
