Answer:
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
