Un río fluye hacia el este. Gracias a tus conocimientos en física diriges tu barco a 53 grados al oeste del norte con una velocidad de 6.0m/s hacia el norte respecto a la costa.(representa el vector y demuestra el proceso matemático completo).

A. ¿Cuál es la velocidad de la corriente?
B. ¿Cuál es la velocidad respecto a la costa?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

Ahot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. compute the velocity of the sandbag at 0.250 s after its release.
