Ok, we've been working on this this whole time. We found the velocity of the 2kg weight after collision to be 4.32 m/s resulting in a final answer of the initial velocity of the 2kg weight being 8.0325 m/s. Is any or all of this right?

I'm still not really sure what you mean. You said the initial velocity of 1.5kg. The initial velocity of the 1.5kg mass is 0. It is still on a pendulum and is struck by the 2kg mass. I need to find the initial velocity that the 2kg mass strikes the pendulum with.

I'm actually checking this forum for my fiancee while she is away from the house, so I'm not exactly sure how to do any of this until she gets back. She would like to know what information she would need to use to find the force acting on the 2kg mass on the inclined plane. In the problem you...

By my initial velocity are you saying that the initial velocity that the 2.00kg mass strikes the pendulum with is correct? Or are you saying that the velocity when the mass approaches the ramp is correct? Is the final velocity of the pendulum at the top of its swing wrong? Sorry, just want to...

Homework Statement A simple pendulum consists of a 1.50 kg mass connected to a cord without any mass or friction. Initially the pendulum is vertically positioned when a 2.00 kg mass collides with it, causing the pendulum to displace vertically upward 1.25 m. After the collision, the 2.00...
