= = A groundhog is being pursued by a vicious coyote. The groundhog begins running from rest and with constant ac- celeration toward the entrance to its underground burrow, which will provide it with safety from the coyote. The groundhog is currently d, 12 m away from the entrance. The coyote is de 19 m behind the groundhog, and is run- ning with a constant speed of v = 8.9 m/s. What constant acceleration a does the groundhog need to maintain in or- der to make it to its burrow just before being caught by the coyote? The symbolic answer must be written in terms of the variables dg, de, and v, but not all of these variables may be needed.
