5. Perusing some older scientific archives, you find some patchy data from a glacier that no longer exists today. The data consists of a velocity profile of the lowermost 100 m of the glacier, shown below (note: "a" means "years," and the data does not extend to the surface of the glacier). A note accompanying the profile states that it is from the ELA of the glacier, where its width was 1.2 km, and its surface slope was 4°. The glacier had an average accumulation rate and accumulation area of 1.6 m/yr and 3.3 km², respectively. How thick was the glacier at its ELA at the time those data were collected, and what was Glens flow law constant for the ice nearest the bed? 2800 2780 Site LB
