Practice Questions
Question 1
An object of mass 4 kg is placed on a frictionless horizontal surface. A horizontal force of 12 N is applied to it. What is the acceleration of the object?
Question 2
A 10 kg object is placed on a horizontal surface. A horizontal force of 25 N is applied, and the object starts accelerating at $2 \, m/s^2$. What is the magnitude of the frictional force acting on the object?
Question 3
An object of mass 8 kg is at rest on a frictionless surface. A horizontal force of 16 N is applied for 4 seconds. What is the final velocity of the object after 4 seconds?
Question 4
A block of mass 6 kg is on a rough horizontal surface. A horizontal force of 18 N is applied, and the block remains at rest. What is the magnitude of the static friction force?
Question 5
An object of mass 3 kg is moving at a constant velocity of $4 \, m/s$ on a rough surface. A horizontal force of $9 \, N$ is applied. What is the magnitude of the frictional force acting on the object?
