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 50 N pull at 45° above the horizontal has vertical component = 35.4 N (approx). Which expression gives the horizontal component?
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?
An aeroplane has thrust 14000 N forward, friction 9500 N backward and air resistance 4500 N backward. What is the resultant horizontal force?
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 people push a table from opposite sides with equal magnitude forces so it doesn’t move. If one person increases their push, what happens to the resultant force?
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 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?
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°))
Two equal forces of 15 N act symmetrically at 30° either side of the vertical. What is the resultant and its direction?
A student applies a 10 N push at the centre of a uniform disk causing no rotation and the disk remains at constant speed. What is the resultant horizontal force?
