Classical Mechanics Level 1

A mouse is running at a speed of $\SI[per-mode=symbol]{8}{\meter\per\second}$ .

From $80 m$ behind, A cat is running after the mouse at a speed of $\SI[per-mode=symbol]{16}{\meter\per\second}$ .

How much time in seconds will take for the cat to catch the mouse?

The answer is 10.

More of a math problem than a physics problem, really.

The distance Tom runs is 16t, where t is the time taken for tom to catch up to Jerry. The distance run by Tom is also 80+ jerry’s time times jerry’s speed.

Formulating an equation:

$16t=8t+80$

taking the 8t term to the other side and simplifying, we get

$8t=80$

dividing both sides by 8;

$t=10 s$

16t = 8t + 80

Solve for t
