What would the acceleration of a freely falling body be measured as in an elevatorthat was moving upward with an acceleration of 2 m/s2? Same question if the elevator was moving downward with an acceleration of 2
4. (1 supporting cable when the cable is (a) moving with an upward acceleration of 2 m/s2 Opts) An elevator cab and its load have a combined mass of 1500 kg. Find the tension in the (b)not moving at all (c)moving with an upward constant velocity 2m/s (d) falling freely
Consider a freely falling object. a. What is the acceleration (in m/s?) after 5 seconds of fall? b. What is the acceleration (in m/s2) after 10 seconds of fall? c. What is the velocity (in m/s) after 5 seconds of fall? d. What is the velocity (in m/s) of 10 seconds of fall?
An elevator is moving upward with a speed of 11 m/s. Three seconds later, the elevator is still moving upward, but its speed has been reduced to 5.0 m/s. What is the average acceleration of the elevator during the 3.0 s interval? 2.0 m/s2, downward 2.0 m/s2, upward 5.3 m/s2, downward 5.3 m/s?, upward
A 96.5-kg person stands on a scale in an elevator. What is the apparent weight when the elevator is (a) accelerating upward with an acceleration of 1.57 m/s2, (b) moving upward at a constant speed, and (c) accelerating downward with an acceleration of 1.79 m/s2?
Suppose a person with a mass of 60 kg is in an elevator standing on a scale that reads in Newtons. Use a free body diagrams of the scale and the person to determine what the scale would read for the following situations: A. If the elevator is descending at 4.9 m/s. B. If the elevator has a downward acceleration of 4.9 m/s2 . C. If the elevator has an upward acceleration of 4.9 m/s2 . explain WHY
A 86.8-kg person stands on a scale in an elevator. What is the apparent weight when the elevator is (a) accelerating upward with an acceleration of 1.72 m/s2, (b) moving upward at a constant speed, and (c) accelerating downward with an acceleration of 1.67 m/s2? (a) Number Units (b) Number Units (c) Number Units
A single mass (m1 = 4.4 kg) hangs from a spring in a motionless elevator. The spring constant is k = 270 N/m. 1) What is the distance the spring is stretched from its unstretched length? 2) Now, three masses (m1 = 4.4 kg, m2 = 13.2 kg and m3 = 8.8) hang from three identical springs in a motionless elevator. The springs all have the same spring constant given above. What is the magnitude of the force the bottom spring exerts on the...
I need the answers for # 5 and #8 2) m m mi Now, three masses m, = 4.8 kg, m2 = 14.4 kg and m2 = 9.6 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above. What is the force the top spring exerts on the top mass? 282.64 N Submit + 3) What is the distance the lower spring is stretched from its equilibrium...
I need answers for #5 and #7 2) m m2 ma Now, three masses (m, = 4.4 kg, m2 = 13.2 kg and mz = 8.8) hang from three identical springs in a motionless elevator. The springs all have the same spring constant given above. What is the magnitude of the force the bottom spring exerts on the lower mass? 86.24 N Submit + 3) What is the distance the middle spring is stretched from its equilibrium length? 79.85 cm...
