Find the velocity, v(t), for an object moving along the x-axis if the acceleration, a(t), is a(t) = 2t + sin(t) and v(0) = 4. (4 points)
a.) v(t) = t2 + cos(t) + 3
b.) v(t) = 2 + cos(t) + 1
c.) v(t) = t2 - cos(t) + 5
d.) v(t) = t2 + sin(t) + 4

! i think the answer is d

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
