The solution would be like
this for this specific problem:
Given: 40
km/h
2 km
t = d / v
t = 2 km / 40 km/h
t = 0.05 h * 60 minutes = 3 minutes
<span>At
this rate, it would take 3 minutes for the red kangaroo to jump 2 km.</span>
We will find the answer using the second law of motion i.e. Force is equal to the product of mass and acceleration.

Where,
- F is force
- M is mass
- A is acceleration
In our case,
Let's solve for M ~




<em>Thus, The mass of object is 36.36 </em><em>grams</em><em>.</em><em>.</em><em>.</em><em>~</em>
