(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?
(b) When the elevator is moving at a constant velocity upward,
which is greater, T or w?
(c) When the elevator is moving upward, but the acceleration is
downward, which is greater, T or w?
(d) Let the elevator...

Description:
A single mass m1 = 3.9 kg hangs from a spring in a
motionless elevator. The spring is extended x = 11 cm from its
unstretched length.
the spring constant of the spring is 347.45 N/m
Now, three masses m1 = 3.9 kg, m2 = 11.7
kg and m3 = 7.8 kg hang from three identical springs in
a motionless elevator. The springs all have the same spring
constant that you just calculated above.
the force the top spring...

An elevator filled with passengers has a mass of 1583 kg.
(a) The elevator accelerates upward from rest at a rate of 1.20
m/s2 for 2.00 s. Calculate the tension in the cable (in
N) supporting the elevator.
(b)The elevator continues upward at constant velocity for 9.22
s. What is the tension in the cable (in N) during this time?
(c)The elevator decelerates at a rate of 0.600 m/s2
for 4.00 s. What is the tension in the cable (in...

An elevator brimming with tourists has a mass of 1900 kg. The
elevator accelerates upward (in the positive direction) from rest
at a rate of 1.8 m/s2 for 2.5 s. The elevator continues
upward at constant velocity for 8.2 s. The elevator experiences a
negative acceleration at a rate of 0.45 m/s2 for 2.1
s.
How far, in meters, has the elevator moved above its original
starting point?

You are designing a high-speed elevator for a new skyscraper.
The elevator will have a mass limit of 2400 kg (including
passengers). For passenger comfort, you choose the maximum ascent
speed to be 18.0 m/s, the maximum descent speed to be 10.0 m/s, and
the maximum acceleration magnitude to be 2.40 m/s2.
Ignore friction.
a) What is the maximum upward force that the supporting cables
exert on the elevator car?
b) What is the minimum upward force that the supporting...

1. A mass of 9.9 kg is resting on a horizontal surface without
friction. A force is applied vertically upward to the mass. What
does the amount of this force need to be in order to begin to pull
the mass off the surface, in Newtons?
2. A mass of 8 kg is resting on a horizontal surface without
friction. A force of 143 Newtons is applied in the +x direction, a
force of 19 Newtons is applied in the...

A force of 720 newtons stretches a spring 4 meters. A mass of 5
kg is attached to the end of the spring and is released from a
position .5 meters below the equilibrium position with a downward
velocity of 8 meters per second. What is the equation of
motion?
Please solve using Differential equations

The force in newtons acting on a kg mass is
Fx=16x3-9x2+8x+14 where x is in meters. Fx is
oriented in the x-direction and acts on the 12kg mass from
x0=0 to xf=5m. If initially at rest and all
of the work of Fx is conserved, find the velocity of the 10kg mass
at xf=10m. report results in m/s

An elevator has a mass of 2,000 kg and is carrying a load of
passengers with a combined mass of 250 kg. A constant friction
force of 3,000 N retards the motion of the elevator. recall; P =
dW/dt
a) How much power must the motor provide to lift the car at a
constant speed of 4 m/s?
b) How much power is required to provide the elevator car with
9.8 m/s^2 of acceleration at 1 m/s vs 4 m/s?
