The initial kinetic energy of the truck is 900,000 kg x m/s? that seems wrong.. but the final should be 0, since final velocity would be 0 m/s.

Homework Statement A 2000 kg truck is moving at a speed of 30 m/s. It hits a haystack and stops in 80m. 1a. What is the original momentum of the truck? 1b. What is the final momentum of the truck? 2a. What is the original kinetic energy of the truck? 2b. What is the final kinetic energy of...

Sorry, I put it in the post now, but I haven't been to class and I'm lost on how to do this type of problem. I've been watching videos on it, but I can't find anything similar to this problem in that the cables connect to two parts of the mass rather than just one point

It's sort of hard to make a drawing to scale; i just drew that picture because it was a given and I thought it would help. I have already converted to Newtons.

Homework Statement Two cables are attached to a 16.00 kg mass, or 160 N (Our teacher told us to use 10 for gravity). The angle between the cable on the left and the ceiling is 48 degrees. The angle between the cable on the right and the ceiling is 22 degrees. Calculate the tension in the cable...

I got it, thanks guys

Homework Statement The angle of the ramp is 30 degrees. The mass is 40 kg. What force must be applied to keep the mass sliding down the ramp at constant velocity. The ramp is frictionless* Homework Equations I have missed the past few lessons in class, so I'm not sure. I do have a bunch of...
