shaking a towel up and down would create what type of wave in
the towel An 80 000-kg airliner is flying at 900 km/h at a
height of 10.0 km. What is its total energy (kinetic +
potential) if the total was 0 when the airliner was at rest on
the ground? Jane and John, with masses of 53 and 62 ,
respectively, stand on a frictionless surface 15 apart. John
pulls on a rope that connects him to Jane, giving Jane an
acceleration of 0.90 toward him. If the pulling force is applied
constantly, where will Jane and John meet? Unless otherwise
stated, all objects are located near the Earth's surface, where
= 9.80 . A girl pushes a 21 lawn mower as shown in the figure .
If F = 33 and N= 42 what is the acceleration of the mower?
Ignore friction. Four identical masses of mass 700 each are
placed at the corners of a square whose side lengths are 11.0
What is the magnitude of the net gravitational force on one of
the masses, due to the other three? A person hums into the top
of a well and finds that standing waves are establis
