Two Masses One on Table, One Hanging

[freeofwork]

Homework Statement

A block of mass1 5.0 kg is on a table that bonds a coefficient of friction of 3.00. Mass1 is attached to Mass2 by a string, and Mass2 is hanging over the table. The system is released from rest for it to accelerate.

Homework Equations

F=ma
F fric = μFnormal

The Attempt at a Solution

$\sum Fx of Mass1$ = F tension - F friction

$\sum Fy of Mass1$ = 0

$\sum Fx of Mass2$ = 0

$\sum Fy of Mass2$ = FW - F tension

Is tension created by the mass1 or mass2?
im guessing both? but that doesn't make any sense...

1. Where is m3?
2. Is coefficient of friction of 3.00 is between the block and table?

no m3...

2. yes

ok wrong interpretation.

Find net force on each block.
Both will accelerate at equal rate for the string is massless and inextensible.

oops one on table, one hanging

Use Newton's 3rd law.
The hanging block will pull the block on the table.
The block on the table will pull the hanging block with equal force.
