Suppose you have a stack of 17 identical steel bars (steel bars have a mass of 1.00kg each). You are required to pull out bar number 16 from the stack (counting from the top of the stack down). Assuming that your assistant holds all other bars in place.   If the coefficient of friction between steel and steel is 0.750, how hard do you have to pull (in N)?

An elevator cab that weighs 20.8 kN moves upward. What is the tension in the cable if the cab's speed is (a) increasing at a rate of 1.10 m/s2 and (b) decreasing at a rate of 1.10 m/s2?

A 8 kg decoration hangs from the ceiling. It is suspended by 2 wires. The first wire forms a 40⁰ angle with the ceiling. The second wire forms a 50⁰ angle with the ceiling.a. Find the tension in the 2 wires (including magnitude and direction) b. Assuming the wire that forms the 40⁰ angle with the ceiling has a length of 0.3 metres, how farbelow the ceiling is the decoration suspended?

Suppose you have a stack of 6 identical steel bars (steel bars have a mass of 1.50 kg each).  You are required to pull out bar number 4 from the stack (counting from the top of the stack down). Assuming that your assistant holds all other bars in place. If the coefficient of friction between steel and steel is 0.710, how hard do you have to pull (in N)?

An elevator filled with passengers has a mass of 1.70 × 103 kg . (a) The elevator accelerates upward from rest at a rate of 1.20 m/s2 for 1.50 s. Calculate the tension in the cable supporting the elevator. (b) The elevator continues upward at constant velocity for 8.50 s. What is the tension in the cable during this time? (c) The elevator decelerates at a rate of 0.600 m/s2 for 3.00 s. What is the tension in the cable during deceleration? (d) How high has the elevator moved above its original starting point, and what is its final velocity?
