Dos masas se encuentran unidas por una cuerda que pasa por una polea. La masa sobre la plataforma horizontal es de 3.38 kg y la masa colgando tiene 6.95 kg. El momento de inercia de la polea es (1/3)MR2, con M =13 kg y radio R =0.41 m. Calcule la aceleración de las masas

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)

What does si stand for, when referring to a system of measurement

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s. assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
