Question 34 (1 point) 10 Position (m) -10 0 1 2 3 6 7 8 9 10 5 Time (s) Consider the motion of an object given by the position vs. time graph shown. For what time(s) is the speed of the object greatest? Word Bank: between 5 -75 At time t = 10$ At time t = 3.0 s At all times from t = 0.0 s- t = 2.0 s At time t = 8.5 s At time t = 4.0 s

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
