30. Un proyectil de artillería se dispara con una velocidad inicial de 300 m/s a 55.0" arriba de la horizontal. Para
evitar una avalancha explota sobre el costado de una
montaña 42.0 s después del disparo. ¿Cuáles son las
coordenadas xy y del proyectil donde explota relativas
a su punto de disparo?​

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
