The lower layer is thought to be hard and rough
Answer:
C) 4.0 m/s²
Explanation:
Given data
- Applied force (F): 120 Newton
- Mass of the object (m): 30 kilograms
- Acceleration of the object (a): to be determined
We can find the acceleration of the object using Newton's second law of motion.
F = m . a
a = F / m = 120 N / 30 kg = 4.0 m/s²
The acceleration of the object is 4.0 m/s².
