A100 kg object hangs from two steel cables, both with radius 1.2 mm. the first cable is 2.5 m long and 2 mm shorter than the second, but the object is horizontal (so they are now the same length). what is the force on the first cable? young's modulus for steel is 2.0 x 1011 n/m2.a : 470 nb : 500 nc : 850 nd : 1000 n

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
