A cannon fires a projectile and it strikes the ground 3.0 km away. Assume the shot starts and lands at the same height. The maximum height the projectile reached was 1.20 km. What was the initial velocity of the projectile?

Respuesta :

Answer:

Step 1: Given Data

Range of the projectile,

The angle of projection,

Step 2: Formula Used

The horizontal range for the projectile is given by,

where

is the range of projectile

is the initial projectile velocity

is the acceleration due to gravity

is the angle of the projectile

Step 3: Calculate the initial velocity

Put the given values in the equation

to find

Step 4: Calculate the maximum range

The maximum horizontal range is achieved when it is fired at an angle of

with the horizontal.

Hence, the bullet will not hit the target

away.
