A volcano lobs a lava blob straight upward with an initial speed of 23.5 m/s.  Neglect air resistance and take upwards as the positive direction for position and velocity. (a) Find the velocity and height (above the volcano) of the lava blob 2.05 s after it is lobbed in the air. (answer: v = + 3.39 m/s; y = 27.6 m) (b) Find the velocity and height (above the volcano) of the lava blob 3.00 s after it is lobbed in the air. (answer: v = - 5.93 m/s; y = 26.4 m) (b) How high does the lava blob rise to? (answer: 28.1 m) (c) How long does it take the lava blob to reach its maximum height? (answer: 2.40 s)
