Answer:
The product of the mass and the volume is known as momentum.
According to the law of momentum, it is stated that the two or more bodies remain in a constant state unless an external force is applied in an isolated room.
Momentum depends on the following:-
Mass
Velocity
Momentum = MASS \ X \ VOLUMEMomentum=MASS X VOLUME
\begin{gathered}momentum = 3000kgm/s\\\\mass = 2000kg\\\\velocity =\frac{momentum}{mass}\\\\v= \frac{3000}{2000} \\\\v= 1.5m/s\end{gathered}
momentum=3000kgm/s
mass=2000kg

Answer:
Explanation:
Given data
Average intensity of sunlight on one day I=700 W/m²
Power P=170 W
To find
Area A
Solution
As we know that:
At tne equator, daylight is always 12 hours.
<span>The further away from the equator, the length of daylight in summer increases, until at latitudes higher than the arctic circle it will be 24 hours at the summer solstice.</span>
<span>The angular momentum L of a rotating wheel with mass m, radius r, moment of inertia I, angular velocity ω, and velocity v of its outer edge:
</span><span>C) Iω</span>
Given the mass of the car and the change in velocity, the impulse exerted on the car by the brakes is 45000kgm/s.
<h3>What is impulse?</h3>
Impulse is simply the product of force and time.
Using the formula of impulse.
Ft = m( v - u )
Given the data in the question;
- Initial velocity v = 25m/s
We substitute our values into the expression above.
Ft = m( v - u )
Ft = 1800kg( 25m/s - 0m/s )
Ft = 1800kg × 25m/s
Ft = 45000kgm/s
Therefore, Given the mass of the car and the change in velocity, the impulse exerted on the car by the brakes is 45000kgm/s.
