- a. Take a moment to be sure that you understand the distinction between Newtons first two laws. How are they different from each other? b. According to Newtons second law. what is the acceleration of an object if there are no forces acting on it? Is your answer consistent with Newtons first law?Because Newtons first law is counterintuitive, it is important to take some time to think about what the law says and about how and why it differs from our intuition. a. Why did the unavoidable presence of friction make it difficult for earlier scientists to come to the conclusion expressed in Newtons first law? b. What is the natural state of an object? c. How much force does it take to keep an object moving at constant velocity?CALCULATE the acceleration of the Falcon 9 Rocket if it takes 70 seconds from launch to reach supersonic speed = 343 m/s. b) Calculate the theoretical acceleration of a 549,054 kg Falcon-9 Rocket, during launch when the thrust of its engines has a net force of 7.6 x 10^6 N. (Hint: use Newton's 2nd law and solve for acceleration) c) Neglecting wind resistance, DETERMINE the theoretical time in seconds it would take for the rocket to reach supersonic speed? (Hint, use your kinematic equation (final) = (initial) + a*t, solve for t). d) Briefly discuss reasons for the difference between your theoretical and actual accelerations and times to reach supersonic speed.
- answers to both question s While we think of weight as "mass", it is actually the pull of gravity on the object. For example, 4.5 kilograms (kg) near Earth is pulled with a force of about 45 newtons, that is, the same force we call "10 pounds" here in the U.S. where the metric system is not as familiar. Now put a 10 lb box at rest on a flat table. What is the total force on the box? mg That's the force of gravity downward on the box. 0 There is no net force on the box. The frictional force F which is μ mg N That's the normal force of the table pushing up on the box. How fast will an object be falling if dropped from rest and allowed to fall for 94 seconds? Use g = 10 m/s2 and give your answer in m/sHello! I’m on this worksheet that’s talking about Newton’s Second Law. Can someone please help me understand this question and what it is asking me to do in order for me to solve it?Can someone give me two physics equation to use on my presentation: one that represents Newton's first law and one that represents Newton's second law? I also need them solved and the steps shown. I know it's a lot to ask but I'd deeply appreciate it.

- Apply Newton’s 2nd Law, in 2 dimensions, to each of the 2 free body diagrams shown. (The two bodies are part of the same situation, and values of and are identical in both cases.) Substitute appropriate expressions for the gravity forces.Do not solve anything, just write down the properly applied formulas.Iaac Newton: A) Inspired the quest for a scientific understanding of human beings as purely physical system. B) All of the above. C) Independently developmentg ( along with Gottfried Lebiniz) the calculus, which would provide a curcial tool for contemporary physics. D) Development a powerful of physics, which would replace Aritotelian physics.Newton’s 2nd Law stipulates that “the sum of all forces acting on an object are equal to the mass times the acceleration of that object.” Given the force diagram below, calculate the acceleration of the object (both magnitude and direction). The object is the smiley face, which weighs 10.2 kg (it’s a very heavy smiley face).
