Answer:
s = 9.81t²
Explanation:
The equation of the vertical displacement of the unicorn at any time t, can be derived using the equation of linear motion
s = Vo.t + 0.5at²
where s is the displacement,
Vo is the initial velocity,
t the change in time from t = 0
a is the acceleration which for bodies falling under gravity without air resistance is 9.81 m/s²
So the equation simplifies to
s = 4.905t²
