- Initial velocity=20m/s
- Final velocity=0m/s(As the car stops)
- Acceleration=-8m/s^2
- Distance=s=26m
We need to verify the thrid equation of kinematics here

The squirrel has a good luck ,Car gets stopped just 1m away from the squirrel .
B) Energy from the sun is the answer, I am sure;
The water cycle is driven primarily by the energy from the sun<span>
. This </span>
solar energy<span>
drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.</span>
Answer:
m = 0.01 kg
Explanation:
Given that,
Momentum of the marble, p = 0.15 kg-m/s
Speed of the marble, v = 15 m/s
We need to find its mass. We know that,
Momentum, p = mv
Where
m is the mass
![m=\dfrac{p}{v}\\\\m=\dfrac{0.15}{15}\\\\m=0.01\ kg](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7Bp%7D%7Bv%7D%5C%5C%5C%5Cm%3D%5Cdfrac%7B0.15%7D%7B15%7D%5C%5C%5C%5Cm%3D0.01%5C%20kg)
So, the mass of the marble is equal to 0.01 kg.
Answer:
constant object, momentum increases directly with speed
Explanation:
whereas kinetic energy increases the square of the velocity due to energy momentum
