2. A stone is thrown vertically upward at 15 m/s. Neglect friction due to the air. A. What is the stone's velocity after 2 Seconds? a. 4.6 m/s upward b. 2.2 m/s upward c. 0 m/s d. 2.2 m/s downward e. 4.6 m/s downward B. How much time, t, does it take for the stone to get back to where it started? a. t = 2.1 s b. t = 3.1 s c. t = 4.1 s d. t = 5.1 s e. t = 6.1 s C. When the stone reaches its maximum height, its acceleration is a. upwards b. zero C. downwards 2. A stone is thrown vertically upward at 15 m/s. Neglect friction due to the air. A.
