Question

the bullet from a rifle travels at a speed of 3*10^4 cm/s. work out the length of time in seconds taken for the bullet to hit a target 54 m away.

Answer 1

Answer:

Here's your answer mate!

Let's go back to our basics. The formula for distance is given by:

Distance = speed x time

Rearranging, we have:

Time = Distance/speed

Let's work in cm

1m = 100cm

So,

54m = 5400cm

Substituting this value (in cm) into the formula for time, we have:

Time

= 5400 / speed

= 5400 / 30000

= 0.18 (secs)

The bullet will take 0.18 sec [that's about 1/5 of a second!] to reach its target.
