Answer:
17.5 N
Explanation:
Given :
- Mass (m) = 2.5 kg
- Acceleration (a) = 7.0 m/s²
To calculate :
Calculation :
• F = ma
→ F = (2.5 × 7.0) N
→ F = 25/10 × 7 N
→ F = 5/2 × 7 N
→ F = (5 × 7)/2 N
→ F = 35/2 N
→ F = 17.5 N towards left
Hence, 17.5 N of net force must act on the book to make it accelerate to the left.
