Question

If you fired a rifle straight upwards at 1000 m/s, how far up will the bullet get?

Answer 1

h = 51020.40 meters

Step-by-step explanation:

Speed of the rifle, v = 1000 m/s

Let h is the height gained by the bullet. It can be calculated using the conservation of energy as :

`(1)/(2)mv^2=mgh`

`h=(v^2)/(2g)`

`h=((1000\ m/s)^2)/(2* 9.8\ m/s^2)`

h = 51020.40 meters

So, the bullet will get up to a height of 51020.40 meters. Hence, this is the required solution.
