Hi, I would really like some help with question 4 using the screenshot provided, thank you.
Please answer the question and its subquestions entirely! This is one question with two subquestions. According to the official Bartleby guidelines, I am alowed to have up to two subquestion! 1) When an ice-skater spins and increases her rotation rate by pulling her arms and leg in, what happens to her kinetic energy? It stays the same. It increases. It decreases. a) A 0.400 kg mass, sitting on a horizontal frictionless surface, is attached to the end of a 0.750 m string. It is whirled around in a circular horizontal path. If the maximum tension that the string can withstand is 450 N, then what maximum velocity can the mass have if the string is not to break? 375 m/s 22.4 m/s 19.4 m/s 29.0 m/s b) A grinding wheel with a moment of inertia of 2 kg-m 2 has a 2.50 N-m torque applied to it. What is its final kinetic energy 10 seconds after starting from rest? 312 J 237 J 156 J 106 J
Hoping for complete solutions since I’m having a hard time with this. Pls skip if unsure or not willing to answer the subitems (these are all connected for one item). Thanks in advanced! A small car with mass 1810 [kg] travels at constant speed on the inside of a track that is a vertical circle with radius 9.00 [m] (see figure on the right). Thenormal force exerted by the track on the car when it is at the top of the track (point ?) is 7.56 X 103 [N] A. What is the normal force on the car when it is at the bottom ofthe track (point A)? B. What is the speed v of the car at point B?
Please can you help me with these questions? 1) A massive space freighter wants to accelerate at 1g. It takes time for the rocket engines to rev up, and turn up to their desired power. The freighter starts from rest, and its acceleration (until it reaches 1g) is: "refer to the picture". The captain wants to reach 1g at time t = T. What must A be, to satisfy a(T) = 1g? 2) The desired final acceleration is now 4g, with a corresponding value for A. Recall the equation in the picture. Acceleration feels like a weight, and a rapid change in acceleration feels like a rapid change in weight. You don't want a too rapid change in weight -- the derivative a'(t) shouldn't be too great. Therefore find T (in seconds) such that the maximum value of a'(t) is 1/80 m/s3. 3) Now, A = 0.6 and T = 2800 seconds. The freighter begins at rest and reaches the desired acceleration in time T. Now calculate and answer v(T) in m/s. Thank you.
Thinking Mathematically: Explore the quantitative dependencies of the acceleration upon the speed and the radius of curvature. Then answer the following questions. Choose the right answer in the parenthesis. 1. As the radius of the circle is doubled, the acceleration is (one-fourth, one-half, two times, four times) the original value. 2. As the radius of the circle is tripled, the acceleration is (one-third, one-ninth, three times, nine times) the original value. 3. If your pig were made to fly at the same speed but in a circular path with a smaller radius, the tension in the string would be (less, more). 4. If your pig were made to fly at the same speed but in a circular path with a smaller radius, the centripetal force on the pig would be (more, less).
Please answer the question and subquestions completely! This is one whole question which has subquestions! According to the official Bartleby guidelines, each question can have up to two subquestions! Thank you! 1) Two bodies, masses m 1 and m 2, are at distance r from each other and attract each other with force F. Find the gravitational force if the distance is doubled. 2F F/2 F/4 4F A) The weight of a 0.50 kg object on the surface of Planet X is 20 N. If the radius of the planet is 4 x 10 6 m, what is its mass? 3.4 x 1019 kg 2.6 x 1022 kg 9.6 x 1024 kg 2.3 x 1025 kg B) How far from the center of the Earth is the point where the net force of the gravitational attraction of the Earth and the moon is zero? The mass of the moon is 1/81 that of the Earth. 8/9 the way to the moon 9/10 the way to the moon 3/4 the way to the moon 80/81 the way to the moon
Inside the command module (the spherical dome at the front) there is a 10.86 m diameter centrifuge, which spins to provide artificial gravity during the long journey. If the centrifuge spins at a rate of 9.2 rotations per minute (rpm), how many g's would this be equivalent to? Be clear and show all your work.
Physical science Simplify please 1. Explain how the results from Parts 1 and 2 verify Newton’s Second Law. If heavier objects were accelerated by gravity at a greater rate, what result would you have expected in measuring the period of the two pendulums of the same length but with different masses for the bob? 2. How close were your results to the known value of g, 9.81 m/s2 based on your percent error? What kinds of errors could have resulted in the difference in your result versus the actual known value of g?
A spaceship has a rotating compartment which gives its passengers artificial gravity. Suppose this compartment is a cylinder with a radius of 8.3 m. For the artificial gravity to be the same strength as what is experienced on Earth's surface, what would the period of rotation of this compartment need to be, in seconds? Be clear and show all your work. (Uniform Circular Motion)
I need help on question 5.5. Explain how you got your answers and why they seem reason
As discussed in class, the moon is receding from the Earth due to tides at a rate of ~4 cm/year. Let’s assume that rate has been constant throughout time (it wasn’t, but we can use it to illustrate some key points). Its current semi-major axis is 384,400 km.a) If the moon formed 4.5 billion years ago and has been receding from the Earth ever since, what was its original semi-major axis? What was its original orbital period?b) What would the apparent size of the Moon have been in the sky as viewed from Earth? That is, in Hmwk 2, you were told the diameter of the Moon spans about 0.5o when viewed from Earth today. What would it have been when the Moon first formed?

Please explain in full detail as I am trying to understand this concept! thank you! a. Sketch a diagram including Earth, Sun, and Mars, with attention to scale of distance (Mars is about 1.5 AU from the Sun) showing a faster trajectory from Earth to Mars than the minimal energy trajectory discussed in the lecture. b. Without doing a calculation, how would the arrival velocity of the spacecraft at Mars for the case in (a) compare to the spacecraft arrival in the class example? The lecture example had the spacecraft arriving at Mars with a velocity of 22.49 km/sec. c. The average velocity of Mars in orbit around the Sun is 24.08 km/sec. Comment on the trade-offs between trajectories, arrival velocities and velocity changes (delta V) required to enter an orbit around Mars.
