The position P is:
ft <u><em> Remember that the position is a vector. Observe the attached image</em></u>
Step-by-step explanation:
The equation that describes the height as a function of time of an object that moves in a parabolic trajectory with an initial velocity is:
Where is the initial height = 0 for this case
We know that the initial velocity is:
82 ft/sec at an angle of 58 ° with respect to the ground.
So:
ft/sec
ft/sec
Thus
The height after 2 sec is:
Then the equation that describes the horizontal position of the ball is
Where
for this case
ft / sec
ft/sec
So
After 2 seconds the horizontal distance reached by the ball is:
Finally the vector position P is:
ft
Answer:
The Number of green bag is 116
Step-by-step explanation:
Given as :
The average number of red , blue and green bags = 136
I.e = 136
Or, red + blue + green = 136 × 3
Or, red + blue + green = 408
Number of red bag = Number of blue bags + 30
Number of green bag = Number of blue bags - 15
Or, ( blue bag + 30 ) + blue bag + ( blue bag - 15 ) = 408
Or, 3 blue bag = 408 - 15
Or, Number of blue bags = 131
Number of red bag = Number of blue bags + 30
Number of red bag = 131 + 30
Or, Number of red bag = 161
Number of green bag = Number of blue bags - 15
Or, Number of green bag = 131 - 15
Or, Number of green bag = 116
Hence The Number of green bag is 116 Answer
