Sagot :
Answer:
11 N
Explanation:
According to Newton's second law of motion, the net force (∑F) on an object is equal to its mass (m) times its acceleration (a). Drawing a free body diagram which shows all the forces acting on the object, we can see there are four forces:
- Weight force mg pulling down
- Normal force N pushing up
- Friction force f pushing left
- Applied force P pulling right
Sum of forces in the horizontal direction:
∑F = ma
P − f = ma
f = P − ma
f = 27 N − (20 kg) (0.8 m/s²)
f = 11 N
