The acceleration function a(t) (in m/s2) and the initial velocity v(0) are given for a particle moving along a line.
a(t)=2t+4,

v(0)=-5

(a) find the velocity v(t) at time t.

v(t)= ? m/s

(b) find the total distance d traveled during the time interval given above.

d=? m

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
