FRQ PRACTICE:

Identify the direction of acceleration

Draw force diagrams to represent the scenario

Write the force equation for the box

Write the torque equation for the disk.

What is the relationship between the string's angular acceleration and tangential acceleration in this scenario?

• They are the same because the string's acceleration is tangential to the disk

• The tangential acceleration is larger because the string's acceleration is tangential to the disk

• The angular acceleration is larger because the string's acceleration is tangential to the disk
