Question

A bullet is shot from a rifle with a speed of 720. m/s what time is required for the bullet to strike a target 3240 m away.

Answer 1

answer

3.5s

Step-by-step explanation:

because 720 is repeated 3times and left number is 360 if we subtract 720-360=360

Answer 2

Answer:

9 seconds

Step-by-step explanation:

v²= 2as

(720)²=2(a)3240

a=80 m/s²

s=ut+1/2at² (u=0)

s=1/2at²

3240=1/2×80×t²

t=9 seconds
