Cool nice job!

Second question: What is the speed of the mass by the time it slides to the bottom of the ramp if theta is 35 degrees, and the coefficient of kinetic friction between the mass and the incline is zero? Related equations: Um, not sure. Kinda stuck on this part lol. Attempt...

Homework Statement A 50 kg mass is released from rest and begins to slide from the top of the incline (2.0 m). Th coefficient of kinetic friction between the mass and the inclines u how much work does gravity do on the mass by the time it slides to the bottom of the ramp if the angle theta...

What is the net force in this case?

Homework Statement A car with a mass of 1100 kg is being pulled by a tow truck exerts a 500 N force on the car and there is a 300 N friction force acting on the car. If the car starts at rest at time t=0, at what time has the truck moved 100 meters? Homework Equations x=v0t + 1/2 at2...

Like how you can apply them to stuff. I just need someone to recap in simple words, I'm not really good at big fat definitions. I'm also asking cause my teacher keeps on emphasizing that Newton's laws 1 & 3 are pretty much useless, and only 2 is important.

they are action-reaction pairs I think, but no, they are separate forces. Remember to label each one with a different name.

Homework Statement I need someone to help me fully understand Newton's Laws. I kinda get his second law, the sum of the forces equals mass times acceleration??, but yea. Homework Equations Newton's First Law Newton's Second Law...

Request post to be deleted, put in a separate topic please. Thanks.

alright, i'll attach something for you Note: Remember that no matter what your object is, it will remain as a box. Do not bother into details, only what that object (or system) it is.

Thanks, I got it. I understand. Thank you.

I'm not sure about this either, but there is an equation for tension...what was it...well, one such formula is F=mg, where m is mass, and g is gravity (9.8 meters/sec squared). Another one is Tension = g * (m1 * m2) / (m1 + m2) * (1 + sin Theta) or Ft = Fg + m

1. A car with a mass of 1100 kg is being pulled by a tow truck. The tow truck pulls the car to the north with a constant 1200 N force, while a friction force pushes the car towards the south. Starting from rest, the truck pulls the car 60 meters toward the north in 25 seconds. What is the...
