A spaceship has a momentum of 20,000 kg·m/s to the left; its mass is 500 kg. What is the magnitude of its velocity?
To find the magnitude of the velocity, we need to use the equation for momentum:
Momentum = mass x velocity
Given that the momentum is 20,000 kg·m/s and the mass is 500 kg, we can rearrange the equation to solve for the velocity:
Velocity = Momentum / Mass
Substituting the given values into the equation:
Velocity = 20,000 kg·m/s / 500 kg
Velocity = 40 m/s
Therefore, the magnitude of the spaceship's velocity is 40 m/s.
To determine the magnitude of the velocity of the spaceship, we can use the formula for momentum:
Momentum = mass × velocity
Given that the momentum of the spaceship is 20,000 kg·m/s to the left and its mass is 500 kg, we can rearrange the formula to solve for velocity:
Velocity = Momentum / Mass
Substituting the values we have:
Velocity = 20,000 kg·m/s / 500 kg
Now, divide 20,000 kg·m/s by 500 kg:
Velocity = 40 m/s
Therefore, the magnitude of the spaceship's velocity is 40 m/s.
P=mv
20 000=500v
Make v the subject of the formula by dividing both sides by 500.
20000÷500=v
v= 40m/s
