Connecting Position, Velocity, and Acceleration Practice Test

$v\left(\frac{\pi}{2}\right)=-1+\int_0^{\pi/2}\cos t,dt$

$v\left(\frac{\pi}{2}\right)=-1+2\cos\left(\frac{\pi}{2}\right)$

$v\left(\frac{\pi}{2}\right)=-1+\int_0^{\pi/2}2\cos t,dt$

$v\left(\frac{\pi}{2}\right)=\int_0^{\pi/2}2\cos t,dt$

$v\left(\frac{\pi}{2}\right)=-1+\int_0^{\pi/2}(-2\sin t),dt$
