Question

norman is pushing a box with force of 40.0 N, forward while kiko is pushing the same box backward with force of 32.0 N. if the box has a mass of 2.30kg , what is its acceleration?

Answer 1

Given:-

• Mass of the box = 2.3 kg
• Force exerted by Mr Norman = 40 N
• Force exerted by Mr Kiko = 32 N

To Find: Acceleration of the box.

Here,

Net force = (Force exerted by Mr Norman) - (Force exerted by Mr Kiko)

or,

Net Force = 40 N - 32 N

= 8 N

We know,

F = ma

→ a = F/m

where,

• a = Acceleration,
• F = Force &
• m = Mass.

so,

a = (8 N)/(2.3 kg)

→ a = (8 kg m/s²)/(2.3 kg)

→ a = (8 m/s²)/(2.3)

→ a = 3.47 m/s² (Approx.)

Thus, the acceleration of the box was of 3.47 m/s².
