Question 12 of 20 The three-toed sloth is the slowest moving land mammal. Assume that on the ground the sloth moves at an average speed of 0.0424 m/s, considerably slower than the giant tortoise, which walks at 0.0544 m/s. After 9.30 minutes of walking, how much further would the tortoise have gone relative to the sloth? Number Units UNITS CHOICES: no units, s, m, m/s, m/s^2, cm/s^2 12

A ball is thrown from an initial height of 4 feet with an initial upward velocity of 29 fus. The ball's height h (in feet) after t seconds is given by the following. h-4+291-167 Find all values of t for which the ball's height is 16 feet. Round your answer(s) to the nearest hundredth. (If there is more than one answer, use the "or" button.) initial height ground - seconds O-O
