PRACTICE / Normal reaction
A scale during downward acceleration
A 60 kg passenger stands on a scale in a lift accelerating downward at 2 m/s².
Find the scale reading in newtons.
Organize the givens & assumptions
- m = 60 kg
- downward a = 2 m/s²
g = 10 m/s²; passenger remains in contact with the scale; downward acceleration is 2 m/s².
- A
- B
- C
- D
