Not at all. It means that the professor and textbook might not be the problem. If the other students in your class aren't having similar difficulties, you need to find another approach to learning the material. You might consider looking at other textbooks, studying with others who aren't...
Are all of the students in your QM class having similar difficulty with the professor and textbook? If not, you probably need to take a hard look at yourself to diagnose the problem.
I took an introductory astronomy course a couple of summers ago. The vast majority of the students in the class were non-science majors. I talked with a couple of students who had dropped a geology class because it was too 'hard'. They were complaining that the astronomy course was also too...
R = ((v0)2 sin(2\theta0)) / g
Rearranging this formula and solving for v0 will give you the initial velocity. You can figure out the final velocity from there.
Not exactly a homework problem, but I'm trying to make sure I understand how the coefficient of static friction works.
Given an object on an inclined plane and a question which asks for the minimum angle at which the object will begin to slide, I know that the formula to use is:
mg...
a) 0.13424051s doesn't leave much time to reach the maximum height and then fall 79m plus the additional height achieved by the 11.0m/s initial velocity.
b) Accelerating to 588.495976m/s in 0.13424051s would require that acceleration due to the force of gravity is 4380.1979 m/s2
c) What...
What drove me back to school was that I've been a software developer for more than 35 years and it's absolute drudgery. I have always been fascinated by science in general and physics in particular, so once the decision was made to take a look at going back to school, the field of study was...
I'm in my 50s and am a sophomore at a 4-year state university. About 25 years ago, I got an associates in electronics engineering, but none of the classes would transfer so I had to start from scratch.
I can honestly say that starting at the bottom helped tremendously. The difference...
