Las pantallas de los controladores de tráfico aéreo, que utilizan radares, despliegan las aeronaves en coordenadas polares. Un avión que pasa, es detectado a 285° en
opuesta a las agujas del reloj desde el norte a una distancia de 5 km desde el radar, luego
30 segundos más tarde es detectada a 225º y 3 km. Calcula la velocidad del avión en km/h.​

Where do magnetic lines of force enter earth?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
