4. [6/8 Points] PREVIOUS ANSWERS An object is dropped from a hot air balloon 800 meters above the ground. The height of the object aer t seconds is given by s(t) = 800 4.9t2. Find the velocity (in meters per second) at times t: 2, t: 3, and t: 4 seconds. v(2) = 496 v m/s v(3) = 29.4 v m/s v(4) = 39.2 m/s What is the velocity (in meters per second) of the object when it strikes the ground? (Round your answer to two decimal places.) v = 42446 x m/5 Submit
