Nothing, I'm completely stumped, I don't even know where to begin. this class has just driven me crazy. I'm having a baby in a few weeks and just cannot figure this stuff out it's completely warn me out.

I don't have a clue, I've been so lost in this class from the beginning. I cannot even figure out where to start and that's the problem. I just need to pass this class. I'm having a baby in a few weeks and just have had so much trouble grasping this stuff.

here is my problem: The surfaces are frictionless. The tracks are 60degrees from horizontal. A 350 kg mass is released from rest on a track at a height 3.2 m above a horizontal surface at the foot of the slope. It collides elastically with a 468 kg mass initially at rest on the horizontal...

I can't figure out what the heck I need to do for this problem. 3) A body oscillates with simple harmonic motion along the x-axis. Its displacement varies with the time according to the equation A=A sin (wt+ pi/3) Where w=pi radians per second, t is in seconds, and a= 7.6m. What is...

I am having trouble understanding how to work this 3 part problem. A 9 kg mass slides to the right on a surface having a coefficient of friction 0.34. The mass has a speed of 4 m/s when contact is made with a spring that has a spring constant 159 N/m. the mass comes to rest after the...

I am having troubles with a physics question. I can't figure out what formula to use to solve the following question: Particle A passes a point with an initial velocity of 14.3 m/s and an acceleration of 4.15 m/x^2. Particle B has a 46 m head start at 7.85 m/s with an acceleration of 2.68...
