A moving car has a momentum of 12,773 kg·m/s. If the car has a mass of 1,103 kg, how fast is it going?

Answer :

Final answer:

After using the momentum formula and rearranging it to solve for velocity (v), it's determined that a car with a mass of 1,103 kg and a momentum of 12,773 kg m/s is moving at approximately 11.58 m/s.

Explanation:

To find out how fast a car with a mass of 1,103 kg is going when it has a momentum of 12,773 kg m/s, we can use the formula for momentum:

p = m × v

Where:

p is the momentum

m is the mass of the object

v is the velocity of the object

In this case, we can rearrange the formula to solve for v:

v = p / m

Plugging in the given values:

v = 12,773 kg m/s / 1,103 kg

After calculating, the velocity v is approximately 11.58 m/s.

Answer:

11.58 m/s

Explanation:

Momentum = mass × speed

p = mv

12,773 kg m/s = (1103 kg) v

v = 11.58 m/s
