Un bloque m (1.00 kg) en un plano inclinado a 5° sin fricción está unido mediante una cuerda delgada que pasa por encima de una polea que no ejerce fricción a un bloque suspendido m (200 g). los bloques se liberan des de el reposo y la masa suspendida cae 1.00 m antes de golpear el piso. determine la rapidez de los bloques justo antes de que m golpee el piso.

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

Contains chemical energy. a. heat b. light c. natural gas
