Consider the Atwood machine of the previous problem. The larger mass is stopped for a moment 2.0 s after the system is set into motion. Find the timeelapsed before the string is tight again.

In a simple Atwood machine, two unequal masses m_1 and m_2 are connected by string going over a clamped light smooth pulley . In a typical arrangement m_1=300g and m_2=600g . The system is released from rest. Consider the Atwood machine of the previous problem. The larger mass is stopped for a moment 2.0 s after the system is set into motion. Find the time elapsed before the string is tight again.

Two unequal masses of 1kg and 2kg are connected by a string going over a clamed light smooth pulley as shown in figure . The system is released from rest .The larger mass is stopped for a moment 1.0 s after the system is set in motion.Find the time elapsed before the string is tight again.

Two unequal masses are connected on two sides of a light string passing over a light and smooth pulley as shown in figure. The system is released from rest. The larger mass is stopped for a moment, 1.0 s after the system is set into motion. The time elapsed before the string is tight again is (g=10 m//s^(2))

Two unequal masses are connected on two sides of a light and smooth pulley as shown in figure. The system is released from rest. The larger mass is stopped 1.0 second after the system is set into motion and then released immediately. The time elapsed before the string is tight again is: Take g=10m//s^(2)

The heavier block in an atwood machine has a mass twice that of the lighter one. The tension in the string is 16.0 N when the system is set into motion. Find the decrease in the gravitational potential energy during the first second after the system is released from rest.

Two equal to masses are connected by a light string passing over a fixed frictionless pully. They are set in motion with uniform speed v. The mass going down is momentarily stopped and then released immediately. Calculate the time that will elapse before the string becomes tight again.
