Answer:
47.5 N
Step-by-step explanation:
Given
- mass, m = 100 kg
- coefficient of static friction, μ(s) = 0.5
- coefficient of kinetic friction, μ(k) = 0.3
- gravity due to acceleration, g = 9.5 m/s²
Solving
- It asks the required force to get it moving ⇒ static friction
- Force required to move = μ(s) x m x g
- F = 0.5 x 100 x 9.5
- F = 95 x 0.5 = 47.5 N
