Thank you for the help though I really appreciate it

I found something online that showed it using that, but I didn't understand it. I have just learned about potential and kinetic energy after finishing a kinematics unit and I think we were supposed to solve it using purely that kinematics and projectile motion knowledge

The ramp is apparently curved and when the marble is shot the vertical velocity is 0 so I can solve for time of the projectile and then find initial horizontal velocity off that

Whoops, never mind I figured it out. Sorry

I understand the basic way of doing it if no energy was lost, but because it is and it adds this whole component of projectile motion I'm feeling a bit lost. At first I wanted to time how long it took from the top of the ramp to when it hit the ground, but I couldn't figure out a way of making...

Thank you for the help I think I understand a) a lot better for b) though is the force that I'm missing the one that is parallel to the slope of the ramp and a component of the m1g force?

Homework Statement The pulley device is used to hurl projectiles from a ramp (Coefficient of Kinetic friction [mu] = 0.26) as illustrated in the diagram. The 5.0 kg mass is accelerated from rest at the bottom of the 4.0 m long ramp by a falling 20.0 kg mass suspended over a friction less...
