desis Posted October 29, 2008 Share Posted October 29, 2008 A fisherman casts his bait into the river at an angle of 25 degrees. As the line unravels, he notices that the bait and hook reach a maximum height of 1.7 m. What was the initial velocity he launched the bait with?

big314mp Posted October 29, 2008 Share Posted October 29, 2008 You need to use the height of 1.7m to calculate the initial y velocity, using the acceleration due to gravity. You then need to use trigonometry to find the initial velocity from the initial y velocity calculated above. Link to comment Share on other sites More sharing options...
ydoaPs Posted October 29, 2008 Share Posted October 29, 2008 How long is the pole? Link to comment Share on other sites More sharing options...
big314mp Posted October 30, 2008 Share Posted October 30, 2008 How long is the pole? At a guess, I'd say the pole is 0m long. I'd also guess that the fisherman didn't drink his milk as a young 'un, and is therefore also 0m tall. Link to comment Share on other sites More sharing options...
