As shown in the figure below, two masses m1 = 5.00 kg and m2 which has a mass 50.0% that of m1, are attached to a cord of negligible mass which passes over a frictionless pulley also of negligible mass. If m1 and m2 start from rest, after they have each traveled a distance h = 1.10 m, use energy content to determine the following.

(b) magnitude of the tension T in the cord

emmatassone · Answer

pose energy conservation to find $$\Delta K$$once you got  this, you know that $$\Delta K= W _{net}= F.\Delta X. \cos \Theta $$ and finally clear the force you want to know.
