AP Calculus BC 9.5: Parametric Position

Practice AP Calculus BC questions on integrating parametric rates and applying an initial position to find a particle’s coordinates.

[Maximum number: 3]

At time $t \geq 0$ , a particle moving along a curve in the x y-plane has position (x(t), y(t)) with velocity vector $v(t)=\left(\cos \left(t^{2}\right), e^{0.5 t}\right)$ . At t=1, the particle is at the point (3,5).

Find the x-coordinate of the position of the particle at time t=2.

$x(2)=3+\int_{1}^{2} \cos \left(t^{2}\right) d t=2.557($ or 2.556 )
