Resultant Forces (GCSE Physics)

A student pushes a trolley with a horizontal force of 15 N. Friction acts opposite with 9 N. What is the resultant force and is the trolley accelerating or decelerating?

A tug-of-war team pulls left with 420 N while the other team pulls right with 300 N. What is the resultant force and direction?

A stationery object is in equilibrium. Which statement about the forces on it is correct?

A box on a table has weight 150 N downward and the table exerts a normal contact force of 150 N upward. What is the resultant vertical force on the box?

A cyclist applies a forward force of 200 N. Air resistance and friction total 200 N backward. What is the cyclist’s acceleration?

A block on a slope experiences gravity component 40 N down the slope and friction 25 N up the slope. What is the resultant along the slope and will the block accelerate up or down?

Two forces of 5 N and 12 N act along the same line in the same direction. What is their resultant?

Two forces of 7 N and 24 N act at an angle of 90° to each other. What is the magnitude of the resultant?

A box is pulled with a 20 N force at 30° above the horizontal. What is the horizontal component of the applied force? (Use cos 30° = 0.866)

Two 8 N forces act on a point separated by 120°. What is the magnitude of the resultant? (Resultant = sqrt(8^2+8^2+2·8·8·cos120°))

A 50 N pull at 45° above the horizontal has vertical component = 35.4 N (approx). Which expression gives the horizontal component?
