Question

25 gram mass is given an upward acceleration of 30 m/s^2 by a rope.

need help finding tension in the rope?
not sure how to set up the problem??


Tension is the reaction force. Clearly you have two forces in opposite directions.


Let T be the tension in the rope. The net force acting is T - W, where
W = M g is the weight.

Newton's Second Law says

T - Mg = Ma

which can be rewritten

T = M (g + a), where

a is the acceleration. Solve for T
