A 1710 N irregular beam is hanging horizontally by its ends from the ceiling by two vertical wires (A and B), each 1.30 m long and weighing 0.320 N. The center of gravity of this beam is one-third of the way along the beam from the end where wire A is attached. Ignore the effect of the weight of the wires on the tension in the wires. a.) If you pluck both strings at the same time at the beam, what is the time delay between the arrival of the two pulses at the ceiling?

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
