a game winning baseball (mass 0.15 kg) approaches at 25 m/s. You want to catch it, but you don't want to hurt your had since that might impede your ability to do physics homework. To lessen the impact you slow it down with your hand over a displacement of 1.1 m as you catch it. What external work must you do on the baseball in J

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
