Answer:
The distance is, y = 489.5 [m/s]
Explanation:
To solve this problem we can use the following equation of kinematics.
where:
Vf = final velocity = 98 [m/s]
Vi = initial velocity = 0
g = gravity acceleration = 9.81 [m/s^2]
y = distance [m]
(98^2) = 0 + (2*9.81*y)
Note: the positive sign of the equation means that the acceleration of gravity acts in the direction of the movement of the object.
9604 = 19.62*y
y = 489.5 [m/s]
<span>why is your formula x=? if i'm reading it right the formula is the height of the object at time t.
That being the case, set your setup (which looks right) equal to 0 and solve for t.
This will tell you how long it takes to hit the ground.
Plug this value of t into the forumla -9.8t+2.8 and that will tell you the speed at time t.</span>
