A 73.0-kg person stands on a scale in an elevator. What does the scale read (in N) when the elevator is at rest? What does the scale read (in N) when the elevator is climbing at a constant speed of 3.0 m/s? What does the scale read (in N) when the elevator is descending at 3.0 m/s? What does the scale read (in N) when the elevator is accelerating upward at 2.4 m/s2 ? What does the scale read (in...
A 74.0 −kg person stands on a scale in an elevator. What does the scale read (in kg) when the elevator is accelerating upward at 3.2m/s^2? What does the scale read (in N) when the elevator is accelerating downward at 3.2m/s^2? What does the scale read (in kg) when the elevator is accelerating downward at 3.2m/s^2?
100 N Does the scale read 100 N, 200 N, or zero
Three forces are acting on a massless rod of length 6 m as shown
in the figure below. The rod and the forces are in the xy plane. If
α=50°, β=30°, and γ = 25°, the torque on the rod about the z-axis
(through the origin of the coordinate system at point C ) is:
A). 35.6 k Nm . B). 46.0 k Nm . C). 71.3 k Nm . D). 56.3 k
Nm
125 N 10 N 30 N
a person stands on a scale inside an elevator at rest. The scale read 800 N. a) The elevator accelerates upward momentarily at the rate of 2 m/s2 . What does the scale read then? I am confused here. please give me a hand preferably with a free body diagram. I am bad at physics
Question 6 A 5.0 m massless rod is held in place at a pivot point. The rod has a small mass of 2.5 kgs attached to it. It is pulled up by an angle of 25 degrees from the horizon and then released. a) Rank the magnitude of the gravitational potential energy of the ball from greatest to lowest and explain your reasoning. (3 points) b) If friction is negligible what is the tension on the rod when + the...

a 71kg man stand on a bathroom scale in an elevator. what does the scale read if the elevator is ascending with an acceleration of 3m/s^2
Sp scale Fe read? Show your calculations and explain. 15. Again two forces are applied to the cart with two different sprine shown below. The spring scale FA still reads 10.5 N. FB 5. The cart moves toward the left with an acceleration toward the left di 2.50 m/s. What does spring scale FB read? Show your calculations and e plain. LAB 5 REALTIME PHYSICS: ME
5. A passenger of mass 85 kg is riding in an elevator while The scale only reads the normal force it exerts on the (Note that 1 b 0.453 kg 4.45 N) a) What standing on a platform scale. does the scale read in pounds (lb) when the elevator is not moving? elevator is moving upward with an acceleration of 3.5 m/s?? c) What does the scale read in pounds (b) when the elevator is same acceleration of 3.5 m/s??...
