Answer:

17.5 N

Explanation:

<h2>Given :</h2>

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

<h2>To calculate :</h2>

  • Force exerted (F)

<h2>Calculation :</h2>

<h3>• F = ma</h3>

→ 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

→ <u>F</u><u> </u><u>=</u><u> </u><u>1</u><u>7</u><u>.</u><u>5</u><u> </u><u>N</u><u> </u><u>towards</u><u> </u><u>left</u>

Hence, 17.5 N of net force must act on the book to make it accelerate to the left.

A man stands on a scale and holds a heavy object in his hands. What happens to the scale reading if the man quickly lifts the ob
Novosadov [1.4K]

Answer:

Explanation:

When he accelerates the heavy object up , the reading increases because an extra downward normal force acts on it, then scale reading returns to the same reading as when standing stationary, and then decreases as although he is lifting the heavy object , the acceleration is decreasing ,so the extra upward normal force acts.
