At the circus, an acrobat is shot straight upwards out of cannon that is 2 meters from the ground. After 2.6 seconds, the acrobat lands in a safety net that is 1.076 meters from the ground. The formula h=−4.9t2+vt+(initialheight) gives the height h of the acrobat (in meters) at any time t seconds after being shot from the cannon at a velocity of v meters per second from an initial height (in meters.) Identify each known quantity that can be substituted into the equation to find the missing value in this scenario. For the missing value, select "not given."
