Para una escena en una película, un conductor acrobatico maneja una camioneta de 1.50 x 10 3 kg y 4.25 m de longitud describiendo medio círculo con radio de 0.333 km. El vehículo debe salir del camino, saltar una cañada de 10.0 m de anchura, y caer en laotra orilla 2.96 m más abajo. ¿Qué aceleración centrípeta mínima debe tener la camioneta al describir el medio círculo para librar la cañada y caer del otro lado?

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?

What is the relationship between ozone and smog?
