Find a solution for the following recurrence relation and initial conditions (use the method of characteristic equation): di = 6d-1-9d1-2, for all integers k> 2; do -1, di = 4. dk=d3k+bk3k do=1=d30+b*0*39=d> d=1 d1=4=d31=3d+3b → d+b=4/3 +b=4/3=d=4/3-154-3/3=1/3 final: dx=3kk3*

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

if you was gonna solve for a, a is a   < -12
