Some later academics question and answer requested students to mention what they presume is the most crucial important element for a student to do if they wanted to get success. Of many reactions, one that that stood out was practice. Successful people are certainly born successful; they become successful through hard work and perseverance. If you wish to attain your goals, keep this in mind! the following are one of the answer and question example that you might possibly work with to practice and elevate your practical knowledge and also give you insights that would help you to preserve your study in school.
A crate is pushed horizontally by a horizontal force 527.018 N . Sliding friction resists the motion, and the kinetic coefficient of friction is 0.17 . The acceleration of gravity is 9.8 m/s 2 . Calculate the acceleration of the crate. Answer in units of m/s 2 .
m= 10 kg a = 52 m / s²
For this problem we must use Newton’s second law, let’s apply it to each axis
F – fr = ma
The equation for the force of friction is
-fr = miu N
N- W = 0
N = mg
Let’s replace and calculate laceration
F – miu (mg) = ma
a = F / m – mi g
a = 527.018 / m – 0.17 9.8
We must know the mass of the body suppose m = 10 kg
a = 527.018 / 10 – 1,666
a = 52 m / s²
They can easily hopefully guide the student resolve the question by applying the questions and answer examples. You may possibly then have a discussion with your classmate and continue the school learning by studying the topic together.
