Answer 2

what?

Answer 3

kinematic equations

y(t) = -1/2 g t^2 +vo *t + ho

where y(t) is the height of the object at time t
g is the gravity constant - 9.81 m/s^2 or 32.2 ft/s^2
vo is the initial velocity in the y direction
ho is the initial height

x(t) = vo *t + xo
x(t) is the location of the object at time t
vo is the initial speed in the x direction
xo is the initial placement of the object
