The acceleration of the object if the net force is decreased = 0.13 m/s²
<h3>Further explanation</h3>Given
A net force of 0.8 N acting on a 1.5-kg mass.
The net force is decreased to 0.2 N
Required
The acceleration of the object if the net force is decreased
Solution
Newton's 2nd law :
The mass used in state 1 and 2 remains the same, at 1.5 kg
- state 1
ΣF=0.8 N
m=1.5 kg
The acceleration, a:
- state 2
ΣF=0.2 N
m=1.5 kg
The acceleration, a:
