- You are standing on a bathroom scale inside an elevator. Your weight is 144 lb, but the reading of the scale is 112 lb. a. What is the acceleration of the elevator? If the acceleration is in upward direction, enter a positive value and if it is in downward direction, enter a negative value. answer in m/s^2 b. see attachedA 12 kg block hanging on a string is pulled upward by the string with an upward acceleration of 6.2 m/s2. What is the tension in the string?You place a crate of mass 35.1 kg on a frictionless 4.90-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.37 s after you released it. What is the angle of the incline? 41.9 degrees 62.9 degrees 37.1 degrees 32.2 degrees
- The coefficient of kinetic friction between this 29 kg box and the floor is 0.25 and the pushing force is 161 N at an angle of 19 degrees below the horizontal. What is the acceleration of the box in m/s2?A man stands on a scale in an elevator that is accelerating upward. The scale reads 973.8 N. When he holds a 44.0 kg box, the scale reads 1449.8 N. What is the man's mass? and What is the magnitude of the acceleration of the elevator?9. A 100 kg man gets in an elevator on the 10th floor. He stands still on a scale, which is placed on the floor of the elevator, before the doors close, and the scale reads a value equal to his weight (the largest force of gravity on him). The doors close, and the elevator starts moving downward toward the 1st floor. The elevator speeds up until it reaches the 8th floor, at which point the elevator travels at a constant velocity, which it maintains until it reaches the 3rd floor, at which point it starts slowing down at a constant rate and stops by the time it reaches the 1st floor. Rank from greatest to least, the following quantities at following floors: 2nd, 5th, 9th. Explain your answers. (a) His mass (the question is asking for a ranking of the person's mass on the 2nd floor vs. the mass on the 5th floor vs. the mass on the 9th floor.) (b) His weight (c) Magnitude of normal force he exerts on the scale (d) Magnitude of normal force he exerts on the elevator floor.
- A person of weighing 0.83 kN rides in an elevator that has an upward acceleration of 0.8 m/s2. What is the magnitude of the force of the elevator floor on the person, in newtons?Two forces (17.0 N at 26.0° south of east, and 52.0 N at 58.0° north of west) are applied to a 200 kg object. If the net force is determined by these two forces, then find the acceleration of the object. magnitude 0.2247 m/s? 0.1932 m/s? С. 0.2053 m/s? 0.1570 m/s? 0.2012 m/s? А. D. В. E. 0.1870 m/s?
