Question

5. 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

Time = distance/velocity, so since distance =3240m and velocity = 720 m/s:  

Time (s) = 3240 / 720 = 4.5s

So The bullet will take 4.5 seconds to reach the target.  

Given that  

speed = 720m/s

s= 3240

speed =distance ÷time  

time = distance ÷ speed  

= 3240 ÷ 720

t =4.5
