Si ustedes empujan juntos una caja de 50 kg a lo largo de una superficie horizontal, y el ángulo con el que aplican sus fuerzas es de 40°. Consideren que entre los dos pueden aplicar una fuerza conjunta de 250 N, ¿cuál es la com- ponente horizontal de dicha fuerza?, ¿con qué aceleración se moverá la caja?

The velocity of a curling stone is due east. what will be the direction of the momentum of the curling stone as it moves?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?
