Resultant Forces (GCSE Physics)

A projectile experiences weight 98 N downward and air resistance 18 N upward at a moment. What is the resultant vertical force?

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

Two equal forces of 15 N act symmetrically at 30° either side of the vertical. What is the resultant and its direction?

A weight of 250 N hangs from two ropes making 60° to the vertical on each side (symmetric). What is the tension in each rope? (Vertical components add to 250 N; use cos 60° = 0.5)

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

A box has three forces in the plane: 10 N right, 6 N up, and 6 N left. What is the resultant force vector?

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 act at right angles: 9 N north and 12 N east. Which of these is the magnitude of the resultant?

Two perpendicular forces of 6 N (east) and 8 N (north) act on a point. What is the magnitude of the resultant force?

A horizontal towbar pulls a disabled car with 1200 N forward. The road applies 1200 N backward. If the towbar force suddenly drops to 900 N, what is the resultant and direction?

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?
