Question

An elevator loaded with tourists has a mass of 1750 kg.

a.) The elevator accelerates upward (in the positive direction) from rest at a rate of 1.55 m/s2 for 2.3 s. Calculate the tension in the cable supporting the elevator in newtons

b.) The elevator continues upward at constant velocity for 8.5 s. What is the tension in the cable, in Newtons, during this time? The elevator experiences a negative acceleration at a rate of 0.65 m/s2 for 2.6 s. What is the tension in the cable, in Newtons, during this period of negative accleration?

c.) How far, in meters, has the elevator moved above its original starting point?

Step 1

The total mass in elevator is 1750kg, the acceleration is 1.55m/s2.

(a) Consider the free body diagram given below.

Step 2

Write the expression for the total force acting on the elevator.

Step 3

(b)As elevator moves up with constant velocity, the accelerati...
