Question

Elle is pushing a box of mass 7.0 kilograms with the force of 25 newtons. If the force of friction is 2.6 newtons, what is the value of acceleration of the box?

Answer 1

Answer : 3.2m/s^2

Explanation : Net force = 25-2.6

• = 22.4Newton
• Mass of the box = 7 Kg
• According to the Newton's second laws of motion Net force= mass x accelation.
• 22.4=7x a
• 22.4= 7a
• a= 22.4/7
• a= 3.2 m/s^2
