Asimple atwood’s machine uses a massless
pulley and two masses m1 and m2. starting
from rest, the speed of the two masses is
4.2 m/s at the end of 4.7 s. at that time, the
kinetic energy of the system is 94 j and each
mass has moved a distance of 9.87 m.
9.87 m
find the value of heavier mass. the accel-
eration due to gravity is 9.81 m/s2 .
answer in units of kg
002 (part 2 of 2) 10.0 points
find the value of lighter mass.
answer in units of kg

Act has a 1200: 5 or 240: 1 turns ratio. it is short circuited. what is the maximum current at 1200a primary if we put a 100ohm resistor across the secondary end of the ct. use it as current source circuit.

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
