A car has a momentum of 20000 km m/s what will the cars new momentum be if it’s doubled by adding more passengers and a good load and it travels at the same velocity
momentum = m*v
So if m is doubled what happens to momentum?
I'm looking for answer
To find the new momentum of the car after doubling its momentum by adding more passengers and load, we need to understand the concept of momentum and how it is calculated.
Momentum is calculated by multiplying an object's mass by its velocity. The formula for momentum is:
Momentum = mass * velocity
In this case, we are given the initial momentum of the car (20000 km m/s), and we need to find the new momentum after doubling it while maintaining the same velocity.
Since velocity is constant, we can assume it remains the same throughout this situation.
Now, let's work through the steps to find the new momentum:
Step 1: Convert the given momentum from km m/s to kg m/s.
Since momentum is calculated as mass times velocity and momentum is typically measured in kg m/s, we need to convert the given value of 20000 km m/s into the standard unit.
To do this, we need to convert kilometers (km) to meters (m). We know that 1 km is equal to 1000 m.
20000 km m/s = 20000 * 1000 m m/s = 20000000 m m/s
So the initial momentum is 20000000 m m/s.
Step 2: Double the initial momentum.
To double the momentum, we simply multiply the initial momentum by 2:
20000000 m m/s * 2 = 40000000 m m/s
Therefore, the car's new momentum, after doubling it by adding more passengers and load while maintaining the same velocity, is 40000000 m m/s.
