Math Problem Statement
The position function of a ball dropped from the top of a 210 meter tall building is given by s(t) = 210 − 4.9t2, where position s is measured in meters and time t is measured in seconds. Compute the average velocity (in m/s) of the ball over the given time intervals. (Round your answers to six decimal places.) [4.99, 5]
Correct: Your answer is correct. m/s [5, 5.01]
Correct: Your answer is correct. m/s [4.999, 5]
Incorrect: Your answer is incorrect. m/s [5, 5.001]
Correct: Your answer is correct. m/s Consider the average velocities above to guess the instantaneous velocity (in m/s) of the ball at t = 5 s. (Round your answer to the nearest integer.)
Correct: Your answer is correct. m/s
