Answer:
C
Explanation:
There are two forces on the table: weight and normal force. Newton's second law:
∑F = ma
N - mg = 0
N = mg
N = (23.5 kg) (9.81 m/s²)
N = 230 N
Answer:
18N
Explanation:
Mechanical Advantage of crowbar (lever), MA = Length of effort arm / Length of resistance arm
Therefore, MA = 28 cm / 4.2 cm = 6.667
Force required to pull the nail, F = Friction force / MA
ie, F = 120 N / 6.667 = 18 N
