Question

How long does a bullet take to travel 12.7cm when going 360 m/s

Answer 1

0.000352 seconds

Step-by-step explanation:

`Speed = (Distance)/(Time) or \\Time = (Distance)/(Speed) = \frac{(12.7)/(100)} {360}`

Time = 0.000352 seconds

Given Distance in centimetres is converted to metres

Answer 2

Answer: 3.53 x 10^-4 s

Explanation:

12.7cm x 1m/100cm = 0.127m

V = d/t

t x V = d

t = d/v = 0.127m/(360m/s) = 0.000353s or 3.53 x 10^-4
