A 71 kg person is standing on a scale in a stationary elevator.Draw an FBD, write...
A 51 kg person standing on a scale in an elevator that is accelerating upwards at 2m/s2. What is the normal force acting on the person (i.e., what would the scale read)? FN = ?
A 75 kg person is standing on a scale in an elevator. What is the reading of the scale in newtons if the elevator is a) at rest b) moving up at a constant velocity of 2.00 m/s c) accelerating up at 2.00 m/s
3. A person with a mass, m 100 kg is standing on a scale calibrated in Newtons inside a completely enclosed tank with negligible mass. The tank is placed on a fixed, frictionless inclined plane. A force, F 290 N is directed up the incline as shown. The tank is released from rest and begins to accelerate. Inside the enclosed tank, the person on the scale has no knowledge of the inclined plane or the force, F 30° e Wlis...

2) A 60.0-kg person rides in elevator while standing on a scale. The elevator is traveling downward but slowing down at a rate of 2.00 m/s2. The reading on the scale is closest to A) 589 N. B) 708 N. C) 469 N. D) 120 N.
4. When a solid object is suspended from a spring scale in air the scale reads 21.7N. The object is then completely submerged in water and the spring scale reads 16.6N. Draw a free-body diagram for the object suspended from the scale in air. You may ignore the very small buoyant force from the air. Using a Newton's 2 nd law equation for the vertical direction on your FBD determine the mass of the object. Draw a free-body diagram for...
A person is standing on and facing the front of a stationary skateboard while holding a construction brick. The mass of the person is 54.0 kg, the mass of the skateboard is 4.10 kg, and the mass of the brick is 2.50 kg. If the person throws the brick forward (in the direction they are facing) with a speed of 15.0 m/s relative to the skateboard and we ignore friction, determine the recoil speed of the person and the skateboard....
A person has a mass of 90kg. He is standing on a scale in an elevator. The elevator is accelerating upward at 5/3 m/s2. What does the scale read on the earth and moon in kg?
A 140 lb person rides in elevator while standing on a scale that reads in slugs. For each part below, draw a free body diagram, write the equations for Newton’s second law and solve. a.) If the elevator accelerates upward at 2.53 ft/s^2, what is the reading on the scale? b.) If the elevator accelerates downward at 1.53 ft/s^2, what is the reading on the scale? c.) If the elevator moves upward at a constant velocity of 2.53 ft/s, what...
if a person was standing on a scale in an elevator that is accelerating down with 1 m/s2 the reading on the scale is 4.5kg DURIN THE DECELERATION OF THE ELEVETOR What is the normal force? and what is the mass of the person, thanks
