Question
How far has the elevator moved above its original starting point in meters?
-------
Problem 2: A block with mass m = 4 kg is sinking with constant acceleration aT = 1.2 m/s2 into the ground. The acceleration due to gravity is g = 9.81 m/s2. Please answer the following questions.
d) Write an expression for the magnitude of the total force of the system in the y-direction, FT, in terms of the forces of the system.
An elevator filled with passengers has a mass of 1650 kg. The elevator accelerates upward (in the positive direction) from rest at a rate of 135 m/s2 for 13 s. the cable supporting the elevator in newtons. The elevator continues upward at constant velocity for 25 s. What is the tension in the cable during The elevator decelerates at a rate of 0.45 m/s2 for 85 s. What is the tension in the cable during this How far has the elevator moved above its original starting point in meters?Explanation / Answer
1) elevator is 4.1895 metres above the starting position
2) the total net force on the system = FT = m*anet = 4*1.2 =4.8 N.
the net force exerted by ground on the block = mg - ma = m*(g-a) =4*(9.81-1.2) = 34.44 N
