Arifle with a muzzle velocity of vo shoots a bullet at a target r away at the level of the muzzle. how high above the target must the rifle be aimed so that the bullet will hit the target? (neglect air resistance.) let vo = 250 m/s and r = 100 m. find h

H = 0.784 m

Explanation:

given,

speed of velocity in x - direction = V₀

Range, R = 100 m                  

let time taken be t

in - x direction  

in- y direction                                              

H = 0.784 m

what is the instantaneous acceleration of

the particle at point b?

0 meters/second?

10 meters/second?

12 meters/second?

velocity imetersisecond

15 meters/second?

20

time (seconds)

answer: 0 meters/second^2

it is a negative acceleration
