Answer Check!!
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.

v(t) = t2 + cos(t) + 3
v(t) = 2 + cos(t) + 1
v(t) = t2 − cos(t) + 5 <---
v(t) = t2 + sin(t) + 4

Answer 1

I think to get the velocity equation from the acceleration you integrate.

v(t) =t^2 -cos(t) + C
4= 0^2 -cos(0) + C
C = 5
looks like you picked the correct answer.
