Please help me solve questions 6 6) A 50 kg person on a scale is in an elevator. The elevator is at rest for 3 seconds. Then it takes 0.8 seconds to accelerate to 6 m/s moving down. It moves elevator then takes 1.2 seconds to slow to a stop. at this speed for 5 seconds. The 6a) Draw an FBD of the situation during both of the accelerations. 42 What is the acceleration of the person during the first...
Interactive Exercises 5.07: Normal Force and Accelerating Particle For a physics class experiment, you place a Red Delicious apple (mass m = 0.100 kg) at rest on a bathroom scale, and place the combination on the floor of an elevator in a tall building. The elevator is initially at rest-see Interactive Fig. 5.7.1 Cable ty Elevator Apple Bathroom scales Interactive Figure 5.7.1: An apple sits on a bathroom scale that rests on the floor of an elevator. Initially, the elevator...
5. What is the tension of the cable of a 2000 kg elevator in City Center if it a) is accelerating up at a rate of 1.5 m/s2? (2 marks) b) is accelerating down at a rate of 1.5 m/s??

1. How much is the period of 1=1.00 m long pendulum on the Moon (g = 1.600 m/s2) 4.97 sec. 2. On a planet X pendulum of the length 0.500 m makes 50.0 oscillations in 1.00 min. Find the acceleration of gravity on the planet X. g = 13.7 m/s2. 3. Find the period of small oscillations of a meter stick suspended by its end near Earth surface (assume g=9.800 m/s2). Notice that this is not a simple pendulum but...
Jake stands in an elevator. As the elevator speeds up departing the 1st floor, and then slowing down approaching 11th floor, Jake feels his weight first increasing, then decreasing. The magnitude of the acceleration of the elevator is the same 3.7 m/s2 in both cases (but the direction is different). If Jake feels 307.4 N heavier when he is departing the 1st floor, than when he is approaching the 11th floor, then what is his true weight? (Weight should be...
m A single mass (m, = 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? cm Submit 2) m ! m m Now, three masses (m, = 4.4 kg, m2 = 13.2 kg and m2 = 8.8) hang from three identical springs in a motionless elevator. The springs all have the same spring constant given above. What is...
