Help me plzzz. i’ll give brainliest!!!
1. In the 1950's, an experimental train that had a mass of 2.50 x 10* kg, was powered across
a level track by a jet engine that produces a thrust of 5.00 x 10' N for a distance of 5.00 x
107 m. What is the final speed of the train if there was no friction?
2. A hockey puck is accelerated, using a hockey stick, over a smooth, level ice surface. The
puck has a mass of 0.400 kg and is moved by the stick for a distance of 0.800 m. What
was the average force applied to the puck if the final speed is 25.0 m/s?

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
