- Consider a person standing on a scale in an elevator. If the elevator accelerates upwards with an acceleration of 1.27 m/s2 and the person has a mass of 79.2 kg, what would the scale read? HINT: you need to take into account the acceleration due to gravity, as well as that of the elevator.arrow_forwardA 2100 kg truck has put its front bumper against the rear bumper of a 2400 kg SUV to give it a push. With the engine at full power and good tires on good pavement, the maximum forward force on the truck is 18,000 N. What is the maximum possible acceleration the truck can give the SUV? At this acceleration, what is the force of the SUV's bumper on the truck's bumper?arrow_forwardAn elevator cab that weighs 20.8 kN moves upward. What is the tension in the cable if the cab's speed is (a) increasing at a rate of 1.10 m/s2 and (b) decreasing at a rate of 1.10 m/s2?arrow_forward
- A person stands on a scale inside an elevator at rest. The scale reads 800 N. The elevator accelerates downward at the rate of 2.4 m/s ^ 2 . What does the scale read then? Calculate answer to one decimal. (use g = 9.8 m/s ^ 2 )arrow_forwardA descending elevator is subject to a constant rate of acceleration, dropping 50.0 m as it goes from an initial velocity of 15.0 m/ downward, to rest. As a percentage of the occupants' masses, what is their apparent weight? 66% 77% 100% 123% 134%arrow_forwardAn elevator weighing 20,000 N is supported by a steel cable. What is the tension in the cable when theelevator is being accelerated downward at a rate of 3.0 m/s2?arrow_forward
- A person weighs -800 N and is traveling downwards in an elevator whilst stood on a bathroom scale (as one does!). The person notices that the scale doesn't always read bodyweight. When arriving at the bottom, the scale reads 840 N. If the person has a mass of 81.5 kg, what is the acceleration of the elevator?arrow_forwardA 74.1-kg crate is suspended between the floor and the ceiling using two spring scales, one attached to the ceiling and one to the floor. If the lower scale reads 120 N, what is the reading of the upper scale? Ignore the weights of the scales.arrow_forwardTwo blocks of masses 20 kg and 8 kg are connected together by a light string and rest on a frictionless level surface. Attached to the 8-kg mass is another light string, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 0.5 m/s 2 what is the tension in the connecting string between the blocks?arrow_forward
- A person stands on a scale inside an elevator at rest. The scale reads 980 N. The elevator then accelerates upward momentarily at the rate of 4 m/s ^2 what does the scale read then?arrow_forwardA woman stands on a scale while riding in an elevator. When the elevator is at rest, the scale reads 60kg. What will be the reading of the scale in kg when the elevator accelerates. (a) upward at 1.2 m/s^2. (b) downward at 1.2 m/s^2. (c) At what acceleration of the elevator would the person appear to be weightless? Draw the FBD of the problem.arrow_forward
