Harry and Angela look from their balcony to a swimming pool below that is 25m?

Question

from the bottom of their building. They estimate the balcony is 50 m high and wonder how fast they would have to jump horizontally to succeed in reaching the pool. What is your answer?

Answer 1

The equations for this are
x(t)=v0*t
since the pool is 25 m away,
25
The fall will be
y(t)=-.5*g*t^2
since y(t)=50
and using g=10
t=sqrt(10)

therefore
v0>25/sqrt(10)
v0>7.9 m/s
