The momentum of a blue whale with a mass of 146,000 kg and a top swimming speed of 24 km/hr is kg-m/s... the answer is:1,022,000 kg*m/s
Answer:
mv
Explanation:
momentum = mass * velocity
The initial velocity of a car that accelerates at a constant rate of 3m/s² for 5 seconds is 12m/s.
CALCULATE INITIAL VELOCITY:
The initial velocity of the car can be calculated by using one of the equation of motion as follows:
V = u + at
Where;
- V = final velocity (m/s)
- u = initial velocity (m/s)
- a = acceleration due to gravity (m/s²)
- t = time (s)
According to this question, a car accelerates at a constant rate of 3 m/s² for 5 seconds. If it reaches a velocity of 27 m/s, its initial velocity is calculated as follows:
u = v - at
u = 27 - 3(5)
u = 27 - 15
u = 12m/s.
Therefore, the initial velocity of a car that accelerates at a constant rate of 3m/s² for 5 seconds is 12m/s.

The dog runs 300240 miles.
<h3>What is the rate?</h3>
Rate refers to the pace at which something happens. We know that the easiest way to obtain the rate is by the use of proportion. Now we have been told that the dog is able to run 500 miles in 12 seconds.
If the dog runs 500 miles in 12 seconds
The dog runs x miles in 1 second
x = 500 * 1/12
x = 41.7 miles
In two hours we have 2 * 60 * 60 = 7200 seconds
If the dog runs 41.7 miles in 1 second
The dog runs x miles in 7200 seconds
x = 41.7 miles * 7200 seconds/ 1 second
x = 300240 miles
