The discussion centers on calculating the tension in a rope required to pull a 1000 kg mass upward with an acceleration of 1 m/s². Two approaches were considered: the first, using the formula T = ma, yields a tension of 1000 N, while the second approach, accounting for gravitational force, results in a tension of 11000 N. The correct method involves applying Newton's second law, leading to the conclusion that the net force must be considered, confirming that the tension is indeed 11000 N.
PREREQUISITESStudents studying physics, particularly those focusing on mechanics and forces, as well as educators looking for examples of tension calculations in real-world applications.
What is Newton's 2nd law telling you?Big-J said:Homework Statement
Tension on the rope to pull a 1000kg mass up at 1m/s^2
Homework Equations
F=ma
The Attempt at a Solution
I'm not sure. It's either
A. T=ma
T=1000(1)=1000 N
or
B. T-mg=ma
T-(1000)(10)=(1000)(1)
T=11000N
Thanks.
directly related to what force?Big-J said:That the acceleration of an object is directly related to force and inversely related to mass. Basically F=ma I guess.
Big-J said:Net force. I think it's option B that I did in my first post.
