Answer:
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:
(5, -12)
Step-by-step explanation:
Put -12 in the equation for y and solve for x:
-12 = -3x +3
4 = x -1 . . . . . . . . divide by -3
5 = x . . . . . . . . . add 1
The solution to the system shown here is ...
(x, y) = (5, -12)
