When thrown from the balloon, the sandbag has a constant horizontal/forward velocity. As the text puts it, "the sandbag continues forward as if it had not been dropped." What this means is that the sandbag has no acceleration in the horizontal plane of motion, so it moves in this direction at a constant speed. So for any time
, the horizontal velocity is given by

In the vertical plane of motion, the sandbag has no vertical velocity until it's released and allowed to fall. As it's falling, however, the sandbag is being pulled down by gravity and is accelerating with magnitude
, so its vertical/downward velocity at time
is given by

So, after 3 seconds have passed, the sandbag has horizontal velocity
and vertical velocity
. If the question is specifically asking about speed you would just ignore the negative signs.
Answer:
Displacement and acceleration
The base of the pyramid has the producers and everything else above the base falls under the consumers category i.e the locusts,frogs and the snake. The grass is the producer, the locust is a consumer, the frog is a special type of omnivore, termed the "life-history omnivore" since they eat both plants and animals but at different times in their lives. In this case they are just omnivores and lastly, the snake is a carnivore.
Answer:
Velocity has both speed and direction. Speed is constant. ... Speed is measured over time.
