Practice Questions

Question 1

A block of mass $5 \, kg$ is on a frictionless surface. Two horizontal forces act on it: $12 \, N$ to the right and $4 \, N$ to the left. What is the block’s acceleration?

Question 2

An object of mass $3 \, kg$ is subjected to a net force that causes it to accelerate at $5 \, m/s^2$. If the same force is applied to an object of mass $6 \, kg$, what will be its acceleration?

Question 3

A $10 \, kg$ object is subjected to two forces acting along the same line: $40 \, N$ to the right and $10 \, N$ to the left. What is the magnitude of the object’s acceleration?

Question 4

A force of $20 \, N$ is applied to a $4 \, kg$ object on a frictionless surface. At the same time, another force of $8 \, N$ acts in the opposite direction. What is the resulting acceleration of the object?

Question 5

A $6 \, kg$ object experiences a force of $18 \, N$ to the right and $2 \, N$ to the left. What is the object’s acceleration?
