Taru and Reiko simultaneously grab a 1.61 kg piece of rope and begin tugging on it in opposite directions. If Taru pulls with a force of 18.0 N and the rope accelerates away from her at 1.24 m/s2, with what force is Reiko pulling? Round your answer to 2 decimal places.
force=mass*acc = 1.61 * 1.24 = 1.9964N
But the force in the other direction has to be counteracted so
Rieko must be pulling with a force of 18+1.9964 = 19.9964N => 20.00N
Is this correct?
