Asteam catapult launches a jet aircraft (from rest) from the aircraft carrier john c. stennis, giving it a speed of 200 mi/h in 3.00 s.
(a) find the average acceleration of the plane.

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied. true or false

Most short-period comets do not have randomly oriented orbits because

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.
