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?

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.

How long is the pole?

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.
