Question

A tiger is running in a straight line. If we double both the mass and speed of the tiger, the magnitude of its momentum will increase by what factor?

Answer 1

Answer:

4

Explanation:

m = Mass of tiger

v = Speed of tiger

When we multiply mass and velocity of an object we get momentum

It is given by

$p=mv$

Now new momentum will be

$p_n=2m\times 2v\\\Rightarrow p_n=4mv$

Dividing the two equations we get

$\dfrac{p_n}{p}=\dfrac{4mv}{mv}\\\Rightarrow p_n=4p$

So, the momentum will increase by a factor of 4
