Force and Motion Dynamics
Which of the following is a vector quantity?
Two forces act on an object: 3N East and 4N North. What is the magnitude of the net force?
Three forces act on an object: 10N at 30 degrees, 15N at 120 degrees, and 5N at 270 degrees. Find the magnitude of the net force.
A book rests on a table. Which force is the normal force?
A block of mass 5 kg is on a horizontal surface with a coefficient of kinetic friction of 0.3. What is the friction force if the block is sliding?
Two blocks connected by a string are pulled across a surface with friction. Find the tension in the string.
