maximum altitude that the bullet will reach is the point at which its velocity
is zero. The equation that may be used in order to determine the altitude is,
D = ((Vi)2 –
Vi and Vf are the initial and final velocities, respectively. g is the
deceleration due to gravity.
the known values,
= ((700 m/s)2 – (0 m/s)2) / (2(-9.8 m/s2))
D = 25000 m
the maximum height is 25000 m.
the time needed to reach it, we use the equation,
= Vi – (g)(t)
0 = 700 m/s
– (-9.8 m/s2)(t)
value of t is equal to 71.43 s.
