A ball is rolled twice across the same laboratory table and allowed to roll off the table and strike the floor. In each trial, the time it takes the ball to travel from the
edge of the table to the floor is accurately measured. (Ignore friction.)
a. In trial A, the ball is traveling at 2.5m/s when it reaches the edge of the
table. The ball strikes the floor 0.391 second after rolling off the edge of
the table. Calculate the height of the table. (Show all work, including the
equation and substitution with units.)

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
