Homework Statement
Three identical blocks connected by ideal strings are being pulled along a horizontal frictionless surface by a horizontal force F_vec. (Intro 1 figure) The magnitude of the tension in the string between blocks B and C is T = 3.00 N. Assume that each block has mass m = 0.400 kg
What is the magnitude F of the force?
What is the tension T:AB in the string between block A and block B?
Homework Equations
F=ma
The Attempt at a Solution
I am unsure of how to approach the first part of the problem. For the second part, since t is the only force acting this the block,
I have: T=ma
I solve for A from the first part of the equation where t is given as follows:
t=ma
3=.400a
a=3/.4
a=7.5 m/s^2
I plugged this into to solve for the other tension as follows:
t=ma
t=.4*7.5
t=3
Mastering physics is saying the tension and the acceleration is wrong. Where did I screw up?
