TEMĂ: Compunerea forțelor de aceeași direcție Reprezintă la scară forțele concurente F1 și F2 de module :

a. F1 = 3N și F2 = 7N, când unghiul dintre ele este de zero grade

b. F1 = 4N și F2 = 9N, când unghiul dintre ele este de 180 grade

Construiește rezultanta celor două forțe concurente pentru fiecare dintre punctele a și b utilizând regula triunghiului.

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?

The boy of mass 30 kg is at r1= 2 meters from the fulcrum. of the girl is 45 kg, at what r2 must she sit so that they are balanced ?
