A golf ball is dropped from rest from a height of 9.50 m. It hits the pavement, then bounces back up, rising just 6.10 m before falling back down again. A boy then catches the ball when it is 1.00 m above the pavement. Ignoring air resistance, calculate the total
amount of time that the ball is in the air, from drop to catch

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
