121. Lava Bombs A volcano shoots out blobs of molten lava, called lava bombs, from its summit, as shown in
Figure 3.33. A geologist observing the eruption uses
a stopwatch to time the flight of a lava bomb that is
projected straight upward. If the time for it to rise to
its maximum height is 2.38 s and its acceleration is
9.81 m/s2 downward, what was its initial speed?

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
