If an airplane is flying north, from what direction would the wind be blowing to most effectively cause the aircraft to veer toward the east?
• What sort of path would it follow for the first second or so?
answer/question/discussion: ->->->->->->->->->->->-> :
it would go north east for the first few seconds
#$&*
• If the wind keeps shifting so as to remain perpendicular to the direction of motion what path will the airplane follow?
answer/question/discussion: ->->->->->->->->->->->-> :
it will eventually be parallel?

A steel ball of mass 60 grams, moving at 80 cm / sec, collides with a stationary marble of mass 20 grams. As a result of the collision the steel ball slows to 50 cm / sec and the marble speeds up to 70 cm / sec.
• Is the total momentum of the system after collision the same as the total momentum before?
answer/question/discussion: ->->->->->->->->->->->-> :
momentum formula = m1 v1 + m2 v2 = m1 v1' + m2 v2'
60g (80cm/s) = 20cm/s 20g
v2-v1 = 50cm/s - 70cm/s = 20 cm/s
it should be the same, because based on the formula?
#$&*
• What would the marble velocity have to be in order to exactly conserve momentum, assuming the steel ball's velocities to be accurate?
answer/question/discussion: ->->->->->->->->->->->-> :
Well I would think the velocity would be the same but not according to my math

momentum is still unclear to me
