In the Atwood machine shown below, m1 = 2.00 kg and m2 = 5.50 kg. The masses of the pulley and string are negligible by comparison. The pulley turns without friction and the string does not stretch. The lighter object is released with a sharp push that sets it into motion at vi = 2.70 m/s downward.
(a) How far will m1 descend below its initial level?
(b) Find the velocity of m1 after 1.80 s.
The electric potential at a position located a distance of 18.6 mm from a positive point charge of 7.50×10-9C and 14.8 mm from a second point charge is 1.10 kV

A street lamp weighs 146 N. It is supported equally by two wires that form an angle of 120° with each other.
Give the force exerted on the bag, to validate your reply.
implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves).
what is the maximum weight of the crate that the system can support? What is the angle needed for equilibrium.
