I’m trying to learn for my Physics class and I’m stuck. Can you help?
1 post in the Discussion thread for the week, and 1 response to a post. The posts must be concise. For example, a post should not be “How do I solve this problem?”. Instead, ask specifics questions, like “Did anyone use the concept of energy to solve this problem?” or “Which coordinate system did you use to solve the problem?
*** note: If I do, the student who posted the solution will earn a grade of zero for the Weekly Discussion AND the Homework assignment.

I tried solving problem 37 using the concept of conservation of energy, but I am not sure if it is a correct approach. Can anyone share which concepts they used to approach the problem?  How do you solve problem 37?

I solved problem 37 by first using the conservation of energy. I included kinetic and gravitational potential energy. I then used the conservation of momentum for the collision of the two objects.
