I am having real problems understanding friction and how it relates to problems. Right now all I have to work with is a Cal-oriented book, but the class I'm in is taught with just Trig. I am completely lost. Your help would be greatly appreciated.
Starting from rest, a 4.33 kg block slides...
futb0l, regarding problem 1a, the answer is incorrect. I have to submit the work via web, so I automatically know if the answer is correct or not. I am so lost in the book, the book is Cal-based, but the teacher only uses Trig in class.
I have never worked problems with mass-spring systems before. I am familiar with Newton's 2nd Law and Hooke's Law. I just do not know how to incorporate friction into what I already know. Friction is a completely new concept that I'm having trouble incorporating into problems.
1.) A light horizontal spring has a spring constant of 182 N/m. A 2.93 kg block is pressed against one end of the spring, compressing the spring 0.144 m. After the block is released, the block moves 0.229 m to the right before coming to rest. The acceleration of gravity is 9.81 m/s2.
a.)...
I am having real trouble understanding friction force. Work I understand. I just don't know how to put them together. Some help would be highly appreciated.
A 16.1 kg block is dragged over a rough, horizontal surface by a constant force of 118 N acting at an angle of 25 degrees above the...
