Newton's Second Law and Force Components Quiz

What is the angle at which the force is applied to the box?

• 35°

• 55°

• 25°

• 45°

What is the mass of the box in the given problem?

• 4 kg

• 5 kg

• 7 kg

• 6 kg

Which force acts directly downward on the object?

• Gravitational force

• Applied force

• Normal force

• Frictional force

Why is the normal force not equal to the gravitational force in this scenario?

• Because the gravitational force is zero

• Because the surface is rough

• Because the applied force has a vertical component

• Because the box is accelerating

What trigonometric function is used to find the y-component of the applied force?

• Cotangent

• Sine

• Tangent

• Cosine

What is the y-component of the applied force?

• 8.6 N

• 15 N

• 12.3 N

• 10.5 N

What is the x-component of the applied force?

• 12.29 N

• 8.6 N

• 15 N

• 10.5 N

What is the calculated normal force acting on the box?

• 58.6 N

• 60 N

• 50 N

• 65 N

Which force is responsible for the acceleration of the box in the x-direction?

• X-component of the applied force

• Gravitational force

• Normal force

• Y-component of the applied force

What is the final calculated acceleration of the box?

• 1.5 m/s²

• 3.0 m/s²

• 2.04 m/s²

• 2.5 m/s²
