Answer:

17.5 N

Explanation:

Given :

  • Mass (m) = 2.5 kg
  • Acceleration (a) = 7.0 m/s²

To calculate :

  • Force exerted (F)

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.
