Calculate the acceleration of this object (picture below) net force:
acceleration:

aₓ = 10 m/s²

∑Fₓ = 20 N

Explanation:

Given data:

Mass of object = 2 Kg

Forces = 25 N, 45 N

Net force = ?

Acceleration = ?

Solution:

∑Fₓ = +F -F

∑Fₓ = 45 N - 25 N

∑Fₓ = 20 N

Net force is in horizontal direction thus acceleration must be in horizontal direction.

Acceleration:

∑Fₓ = maₓ

20 N = 2 Kg × aₓ

aₓ = 20 N/2Kg

N = kg.m/s²

aₓ = 10 kg.m/s²/Kg

aₓ = 10 m/s²
