An elastic string of negligible mass has one end fixed to a
ceiling at point A. The other end, point B, which is attached to a
particle of mass 3 kg, is in a position such that it is vertically
below point A, with the distance AB equal to 0.7 m. The mass is
released from rest. If the modulus of elasticity of the string is
35 N and its natural length is 1.3m find i) The distance of the...

A worker stands a distance
d = 0.250 m
from the left end of a beam as shown in the figure. The beam is
supported by three ropes. Find the tension in each rope (in N).
Assume the beam is uniform, with length L = 2.00 m and
mass 34.0 kg, and the weight of the worker is 710 N. (Due to the
nature of this problem, do not use rounded intermediate values in
your calculations—including answers submitted in
WebAssign.)...

A lumberjack (mass 98 kg) is standing at rest on one end of a floating log (mass = 290 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +3.9 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. Neglect any friction and resistance between the logs and the water. (a) What is the velocity of the first log just before...

A mass hanging from one end of a spring whose other end is fixed to the roof, undergoes simple harmonic motion x(t)=2.4sin(0.6t)x(t)=2.4sin(0.6t). Now if the mass is pulled down from its equilibrium position by a distance 2 times its previous amplitude and released at time t=0t=0, its displacement as a function of time is A.2.4cos(1.2t)2.4cos(1.2t) B. 2.4sin(1.2t)2.4sin(1.2t) C. 4.8sin(1.2t)4.8sin(1.2t) D. 4.8cos(0.6t)4.8cos(0.6t) E. 4.8cos(1.2t)4.8cos(1.2t) F. 4.8sin(0.6t)

A 4.00 kg ball is dropped from a height of 15.0 m above one end of a uniform bar that pivots at its center. The has mass 9.00 kg and is 4.00 m in length. At the other end of the bar sits another 4.00 kg ball, unattached to the bar. the dropped ball sticks to the bar after the collision. Assume that the bar is horizontal when the dropped ball hits it. How high will the other ball go...
