Home is like a shelter where it keeps us safe.
Answer:
5.0 m
Explanation:
The velocity of the object at time t is given by

where a=9.8 m/s^2 is the acceleration of gravity and t is the time. If we substitute v=7 m/s, we can find the time t at which the velocity became 7 m/s:

The height of the object at time t, h(t), is given by the equation

where
is the initial height. By substituting t=0.71 s inside the equation, we find the height h(t) at which the velocity is 7 m/s:
