5. [-/11 Points] DETAILS LARCALC11 1.R.038. MY NO For this exercise, use the position function s(t) = -4.9t + 360, which gives the height (in meters) of an object that has fallen for t seconds from a height of 360 meters. The velocity at time t = a seconds is given by lim s(a) - s(t) t- a a - t When will the object hit the ground? At what velocity, v, will the object impact the ground? m/s # Show My Work (Optional)
