- When constructing a free‑body diagram, why is it a good idea to choose a coordinate system so that the motion of an object is along one of the axes?A rocket in in deep space. A ball is attached to a spring inside the rocket, and the other end of the spring is attached to the back wall of the rocket. The rocket starts accelerating. (a) Choose values for the following. None of them can be 0. The acceleration of the rocket The mass of the ball iii. The spring constant of the spring (b) Draw the Free Body Diagram of the ball. (c) Label the origin and axes. (d) Calculate the compression of the springJeanine, who has a mass of 45 kg, rode a roller coaster through a loop with a radius of 35 km . Assume the roller coaster maintained a constant speed of 48m/s. Draw a free-body diagram of the scenario below. Include the forces at the: • top • bottom • sides
- Two blocks each of mass m are fastened to the top of an elevator as in the figure below. The elevator has an upward acceleration a. The strings have negligible mass.

T = T2 = (b) Compare the two tensions and determine which string would break first if a is made sufficient large. This answer has not been graded yet (c) What are the tensions if the elevator cable breaks?

The total mass of Cart 2, cart plus fridge, is three times the total mass of Cart 1, cart plus person.

- Consider the two-body situation at the right. A 100.0-gram hanging mass (m2) is attached to a 325.0-gram mass (m1) at rest on the table. The coefficient of friction between the 325.0-gram mass and the table is 0.215. Determine the acceleration of the system and the tension in the string.Could you tell the 34th solutionConsider a large textbook with mass m = 6 lb = 2.72 kg at rest sitting on a wooden table. (a.) Draw a free-body diagram for this stationary textbook. Make sure to include all the forces acting on the textbook, and clearly indicate in your diagram the net force (To be clear about it, I’m just looking for an algebraic expression of either F⃗net = m⃗a or F⃗net = 0 to appear in the diagram. I’m not looking for a number here). Also make sure to include a net force vector in your diagram (if F⃗net ̸= 0). (b.) Now, suppose one side of this table is lifted up with a pulley and fixed in place so that the table effectively acts like/becomes an inclined plane (that is, a ramp). The angle of the incline, measured from the horizontal, is measured to be 30◦. Assume the table is NOT frictionless. Take the coefficients of static and kinetic friction between the book and table to be μs = 0.4 and μk = 0.2, respectively. Assume that this angle is large enough such that the book overcomes static…
- 1. A ball with a mass of 10 kg is hanging from a long string that is tied to the ceiling of a train car traveling eastward on horizontal tracks. An observer inside the train car sees the ball hang motionless. Draw a clearly labeled free-body diagram for the ball if (a) the train has a uniform velocity, and (b) the train is speeding up uniformly. (c) Is the net force on the ball zero in either case? Explain. (d) If the train stops from 60 km/h velocity within 5 s, draw a clearly labeled free-body diagram for the ball and compute for the tensional force on the string (assumes that the string didn't break).Question 6 This is one of three questions about #18: 18. A scale in the elevator's floor measures the weight of the passengers, and it has the correct value when the elevator is not moving. The combined mass of the passengers is 572 kg. What will the scale read if. c) the elevator is accelerating down at a constant rate of 1.5 m/s?? (This is asking for the solution to 18c in the worksheet.) Your answer: 860 N 4700 N 5600 N 6500 N Clear answer
