A simple At wood machine composed of a single pulley and two masses `m_(1)` and `m_(2)` is on an elevator. When `m_(1)`=44.7 kg and `m^(2)`=45.3 kg, it takes 5.0 sec for mass `m_(2)` to descend exactly one meter from rest relative to the elevator. What is the elevator's motion?

Three blocks m_(1), m_(2) , and m_(3) are arranged as shown in fig. if m_(2)=5 kg and m_(3)=8kg , at what value of m_(1) will 8kg mass be at rest?

Two masses m_(1) and m_(2) are attached to a string which passes over a frictionless smooth pulley. When m_(1)=10kg,m_(2)=6kg , the acceleration of masses is

Two masses m_(1) and m_(2) which are connected with a light string, are placed over a frictionless pulley. This set up is placed over a weighing machine, as shown. Three combination of mass m_(1) and m_(2) are used, in first case m_(1) =6kg and m_(2)=2 kg , in seconds case m_(1)=5 kg and m_(2)=3 kg and in third case m_(1)=4 kg and m_(2)= 4 kg . masses are held stationary initially and then released. if the reading of the weighing machine after the release in three cases are W_(1),W_(2) and W_(3) respectively then:

In the figure, pulleys are smooth and strings are massless, m_(1) =1 kg and m_(2)=(1)/(3) kg. To keep m_(3) at rest, mass m_(3) should be

A pulley fixed to the ceiling of an elevator car carries a thread whose ends are attached to the masses m_(1) and m_(2) . The car starts going up with an acceleration a_(0) . Assuming the masses of the pulley and the thread as well as the friction to be negligible, find: (a) the acceleration of the load m_(1) relative to the elevator shaft and relative to the car (b) the force exerted by the pulley on the ceiling of the car. Given m_(1) gt m_(2) .
