1. The position of a particle is given by the function below. When does the particle reach the velocity of -120.88 m/s? s ( 1) =1'-2412 -101, 120 2. The function v(t)=cos(t)sin(t) gives the velocity of a particle moving along a line, where v is in feet per second and t is in seconds. Determine if the particle is speeding up or slowing down at time t = 5.5. Explain how you determined your
