Calculate the normal force, N acting in a elevator if his mass is 72.1kg and the acceleration due to gravity is 9.81m/s2. the elevator has constant velocity
As the velocity of elevator is constant, the acceleration is zero.
Normal force = mg = (72.1*g) = 72.1*9.8 = 706.58 N.

A simple elevator ride can teach you quite a bit about the normal force as this rider below can (hopefully) tell you. There are three different scenarios given, detailing the rider\'s experience in an unnamed hotel. For each scenario, calculate the normal force, FN,1-3, acting on the rider if his mass is m = 76.6 kg and the acceleration due to gravity g = 9.81 m/s2. In scenario 1, the elevator has constant velocity. In scenario 2 the elevator is moving...
(a) An elevator of mass m moving upward has two forces acting on it: the upward force of tension in the cable and the downward force due to gravity. When the elevator is accelerating upward, which is greater, T or w? T w Both forces are equal. (b) When the elevator is moving at a constant velocity upward, which is greater, T or w? T w Both forces are equal. (c) When the elevator is moving upward, but the acceleration...

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...
2, When you divide the total distance and total time for a trip, you calculate a(n) average acceleration instantaneous speed average speed non-uniform speed constant speed 3. A heavy object and a light object are dropped from rest at the same time in a vacuum. The heavier object will reach the ground It depends on the shape of the object at the same time as the lighter object It depends on the mass of the object after the lighter object...
Consider applying Newton’s second law to a man riding an elevator (perhaps to calculate his acceleration). Which of the following forces must be considered? Choose all that apply. The force that the man's head exerts on his neck The force that the man's feet exert on the floor of the elevator The force of gravity on the man The force that the elevator floor exerts on the man's feet The force the elevator cable exerts on the elevator car The...
Consider a constant total force of 1,216 N acting on an object. If the acceleration of the object is 9 m/s2, what is the mass in kg of this object if all other forces equal zero?
