Now, the bears I live with average, the males, eight to twelve hundred pounds [360 to 540 kg]. They're the largest bears in the world. They've been clocked at 41 [mph] and they've run a hundred meter dash in 5.85 seconds, which a human on steroids doesn't even approach. 1. Compute the speed of a grizzly bear using Mr. Treadwell's hundred meter dash statement. 2. Compute the momentum of a grizzly bear using the speed you calculated in part 1 and the average mass of 450kg. 3. How fast would a 250 lb man have to run to have the same momentum you calculated in part 2? (You may have to convert units first). 4. How fast would a 4000 lb car have to drive to have the same momentum you calculated in part 2? (You may have to convert units first)
