Two forces, f⃗ 1 and f⃗ 2, act at a point. f⃗ 1 has a magnitude of 8.80 n and is directed at an angle of 58.0 ∘ above the negative x axis in the second quadrant. f⃗ 2 has a magnitude of 6.60 n and is directed at an angle of 53.9 ∘ below the negative x axis in the third quadrant. part a what is the x component of the resultant force?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
