Ahockey puck (1) of mass 180 g is shot west at a speed of 8.40 m/s. it strikes a second puck (2), initially at rest, of mass 144 g. as a result of the collision, the first puck (1) is deflected at an angle of 38° north of west and the second puck (2) moves at an angle of 40° south of west. what is the magnitude of the velocity of puck (1) after the collision?

Consider two metallic rods mounted on insulated supports. one is neutral, the other positively charged. you bring the two rods close to each, but without contact, and briefly ground the the neutral rod by touching it with your hand. show answer correct answer what would be resulting charge (if any) on the initially neutral rod

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?
