HOMEWORK PROBLEMS Chapter 4: THE LAWS OF MOTION PART-A: Hand in your answers in class on scantron on Wednesday 22 September-2010. The questions have been numbered so you can use the back side of an older scantron. Write your name‚ class (1401) and HW # 4 on the scantron. 1. A horizontal force of 95.0 N is applied to a 60.0-kg crate on a rough‚ level surface. If the crate accelerates at 1.20 m/s2‚ what is the magnitude of the force of kinetic friction acting on the crate? (a) 23.0 N (b) 45.0 N

Bernoulli’s Principle and Newton’s Laws of Motion Embry-Riddle University Bernoulli’s Principle and Newton’s Laws of Motion Bernoulli’s Principle In fluid dynamics‚ Bernoulli’s principles states that an increase in the speed of the fluid corresponds to a decrease in pressure of the same fluid. Similarly‚ the decrease in pressure corresponds to a loss in the potential energy of the fluid. The principle is applicable to various types of fluids‚ which leads to Bernoulli’s

Isaac Newton In this essay the life of Isaac Newton is uncovered. It goes into depth about where he lived‚ where he moved‚ his family and who he lived with. Within the first few paragraphs you will learn about his education‚ lifestyle‚ and family. He had a challenging childhood as his mother was in and out of his life and was widowed two times. He also went in and out of school although he never stopped learning and excelling himself. In the second set of paragraphs his multiple accomplishments

Calculation: Use Kepler’s Third Law (M=(4π^2 r^3)/(GP^2 )) to calculate the mass of “Object X” from the orbit of its moon—whose orbital radius (r) is 64‚780 kilometers and whose orbital period (P) is 38.200 days—and knowing that the gravitational constant G= 6.673×〖10〗^(-11) m^3 〖kg〗^(-1) s^(-2)(where m= meters‚ kg= kilograms‚ and s=seconds). Express the answer in units of Earth Mass (M_Earth)‚ knowing that M_Earth= 5.980×〖10〗^24 kg. (Hint: first express r and p in standard units: meters and seconds

Sir Isaac Newton PRS MP (25 December 1642 – 20 March 1727) was an English physicist‚ mathematician‚ astronomer‚ natural philosopher‚ alchemist and theologian‚ who has been considered by many to be the greatest and most influential scientist who ever lived.[8] His monograph Philosophiæ Naturalis Principia Mathematica‚ published in 1687‚ laid the foundations for most of classical mechanics. In this work‚ Newton described universal gravitation and the three laws of motion‚ which dominated the scientific

Newton’s First Law of Motion states explains that a force is needed to change the motion of an object. It states that objects do not move or change their speed unless a force acts upon them. The first law applies to gymnastics in some areas‚ particularly on the bars and the balance beam. For example‚ on the bars when a gymnast performs a giant she is doing complete revolutions around the high bar while keeping her body straight. In order to begin this skill she had to apply some force to get into

August 25‚ 2014 Sir Isaac Newton Sir Isaac Newton was an English physicist and mathematician. He was born December 25‚ 1642. Newton is credited with creating calculus with Gottfried Wilhelm Leibniz. Newton is recognized as one of the most influential scientists of all and an important person in the scientific revolution. Isaac Newton first described a method for approximating the real zeros of a function in text in 1671 but his work was not published until 1736. Meanwhile‚ a man by the name of

Research Paper on Pascal’s Law Blaise Pascal’s findings and contributions to the behavior of fluid in an enclosed space have been an invaluable and important concept in fluid mechanics and its applications especially in the automotive industry‚ mechanical engineering‚ and hydraulics. Pascal’s law or the principle of transmission of fluid-pressure that was proposed by Blaise Pascal. According to Bloomfield‚ the law is a principle in fluid mechanics that states that for a particular position within

Math Sir Isaac Newton On Christmas day in 1642 a premature baby by the name of Isaac Newton was born. Isaac was born in Woolsthorpe‚ Lincolnshire‚ England and attended day school there while living with his grandmother. When Isaac was about thirteen‚ he went away to Grammar School in Grantham where he noticed his interest in chemicals. In 1661‚ he went to Cambridge University and stayed there until 1696 (with some gaps due to the plague). Within his Cambridge years‚ Isaac

primarily about Newton’s second law of motion. Newton’s second law of motion states that a net force is required for a body to have acceleration. If a net force is applied on an object‚ then the object will accelerate with respect to the direction of the said force. The body’s acceleration is directly proportional to the net force and inversely proportional to its mass. The experiment conducted was used to verify the relationships specified in Newton’s second law of motion. There were 3 trials‚ and
