The way I understood is it is by taking ma and setting it equal to mv^2/r and solving for v. With this I got answer choice number 9, sqrt(glsinTHETA). But it's wrong. Can anyone direct me in the right direction to solving this deceptively easy problem? Thanks in advance.

No. Start by writing down two equations: one for the requirement of the sum of the forces in the vertical plane, and one for the sum of the forces in the horizontal plane. In otherwords, apply Newton's second law seperately to the vertical and radial planes.Garen said:
"Multiple-Choice Doozie" is a type of multiple-choice question that presents complex or tricky scenarios to test the critical thinking and problem-solving skills of the test-taker.
"Multiple-Choice Doozie" questions are designed to challenge the test-taker's understanding and application of concepts, rather than simply testing their knowledge of facts. They often require more analysis and critical thinking to arrive at the correct answer.
Yes, "Multiple-Choice Doozie" questions are generally considered more difficult because they require higher-order thinking skills to solve. They may also have more than one correct answer, making them more challenging to score.
To prepare for "Multiple-Choice Doozie" questions, it is important to practice critical thinking and problem-solving skills. You can also review past examples of these types of questions to get an idea of the format and level of difficulty.
Yes, there are some strategies that can help when answering "Multiple-Choice Doozie" questions. These include reading the question carefully, eliminating obvious incorrect answers, and using process of elimination to narrow down options.
