con una persona subio en el punto mas bajo de la rueda de la fortuna considera que la rueda tiene 12 metros de diametro y que ha avanzado un cuarto de vuelta hacia la derecha desde que la persona subio marca coin rojo la trayectoria de la persona marca con azul el desplazamiento calcula la distancia hasta ese punto calcula la magnitud del movimiento indica la direccion del desplazamiento

Abearing is designed to a reduce friction b. support a load c. guide moving parts such as wheels, shafts and pivots d. all of the above

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to. in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
