The acceleration of the crate after it begins to move is 0.5 m/s²
We'll begin by calculating the the frictional force
Mass (m) = 50 Kg
Coefficient of kinetic friction (μ) = 0.15
Acceleration due to gravity (g) = 10 m/s²
Normal reaction (N) = mg = 50 × 10 = 500 N
Frictional force (Fբ) =?
Fբ = μN
Fբ = 0.15 × 500
Fբ = 75 N
- Next, we shall determine the net force acting on the crate
Frictional force (Fբ) = 75 N
Force (F) = 100 N
Net force (Fₙ) =?
Fₙ = F – Fբ
Fₙ = 100 – 75
Fₙ = 25 N
- Finally, we shall determine the acceleration of the crate
Mass (m) = 50 Kg
Net force (Fₙ) = 25 N
Acceleration (a) =?
a = Fₙ / m
a = 25 / 50
a = 0.5 m/s²
Therefore, the acceleration of the crate is 0.5 m/s²
