Question

Two crates, one with mass 4.00 kg and the other with mass 6.00 kg, sit on the frictionless surface of a frozen pond, connected by a light rope. A woman wearing golf shoes (so she can traction on the ice) pulls horizontally on the 6.00 kg crate with a force F that gives the crate an acceleration of 2.50 m/s^2. a) What is the magnitude of the force F? b) What is the tension in the rope connecting the two crates?

Answer 1

$F=(m_1+m_2)a=25~N,$

$T=F=25~N.$
