A 100 N force is applied to a 50 kg crate resting on a level floor. The coefficient of kinetic friction is 0.15. What is the acceleration of the crate after it begins to move

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
