At time t = 0, a particle is located at the point (8,4,7). It travels in a straight line to the point (3,9,6), has speed 3 at (8,4,7) and constant acceleration negative 5i + 5 j - k. Find an equation for the position vector r(t) of the particle at time t.
we know that particle has constant accleration vector 5i+5j-k
now we know that
integrate both side
we know that at t=0 we have position 8i+4j+7k and sp...
