Newton's Laws of Motion

Which of the following objects has the most inertia?

What is the net force on a 5 kg object accelerating at 2 m/s²?

A 10 kg object is subjected to a force of 50 N to the right and a frictional force of 10 N to the left. What is the acceleration of the object?

A box of mass $m$ is pulled along a horizontal surface with a force $F$ at an angle $\theta$ above the horizontal. The coefficient of kinetic friction between the box and the surface is $\mu$. What is the magnitude of the normal force?

A 2 kg mass moves in a circle of radius 1 m at a speed of 3 m/s. What is the centripetal force?

A car is moving around a flat, circular track of radius $r$ at a constant speed $v$. What is the minimum coefficient of static friction $\mu_s$ between the tires and the road that will allow the car to move without slipping?

A book rests on a table. What is the reaction force to the weight of the book?

A person pushes a box across a floor. Identify the action-reaction pair.

A block of mass $m$ is placed on an inclined plane with an angle of $\theta$ relative to the horizontal. If the coefficient of kinetic friction between the block and the incline is $\mu$, what is the magnitude of the friction force acting on the block as it slides down the incline?

A block of mass $m_1$ rests on an inclined plane connected to a second mass $m_2$ hanging vertically via a pulley. The inclined plane makes an angle $\theta$ with the horizontal. Assuming the surface of the inclined plane is frictionless, what is the acceleration of the mass $m_1$ up the incline if $m_2$ is accelerating downwards?
