Need some help with a fairly basic tethered objects question and I'm getting a different answer to the one provided.
A block weighing 2kg is accelerated by a falling weight (0.5kg). Calculate the tension in the cord if 2kg block experiences a fricitional force of 1.5N as it slides on the table.
First I considered the whole body assuming it experiences uniform acceleration. The only two forces acting on the whole body are the frictioon force and gravity. Therefore I calculated the resultant force to be 0.5 x 9.8 subtract 1.5. Meaning the system was accelerating at 1.36 m/s^2.
Then I looked at the forces acting on the 2kg block (drag and tension). and then Fresultant= 2 x 1.36 and calculated the tension to be 4.22 N.
The answer is 4.3N (yeah i know HUGE difference) but this answer couldn't be due to rounding
EDIT they used g as 10 instead of 9.8 -_____-
