THE PRACTICE STUDIO
Go slowly. Ask why. Make it yours.
PRACTICE / Tension
The string does not read either weight
Masses 4 kg and 1 kg hang over an ideal pulley and accelerate freely.
Find the string tension.
Organize the givens & assumptions
- mheavy = 4 kg
- mlight = 1 kg
g = 10 m/s²; ideal massless pulley and string; taut string gives equal acceleration magnitudes.
