6) A force Fis exerted on a 5 kg block to move it across a rough surface, as 1 point

shown. The magnitude of the force is initially 5 N, and the block moves at a

constant velocity. While the block is moving the force is instantaneously

increased to 12 N. How much kinetic energy does the block now gain as it

moves a distance of 2 m?*

Which of the following is an example of motion in two dimensions?

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.
