Understanding Momentum
Momentum (p) is a measure of an object's mass in motion. It's calculated using the following formula:
* p = m * v
* p = momentum
* m = mass
* v = velocity
Calculations
1. Bullet:
* Mass (m) = 10 g = 0.01 kg
* We need the velocity (v) of the bullet to calculate its momentum.
2. Cricket Ball:
* Mass (m) = 400 g = 0.4 kg
* Velocity (v) = 90 km/h. We need to convert this to meters per second (m/s) for consistency:
* 90 km/h * (1000 m/km) * (1 h/3600 s) = 25 m/s
Determining Higher Momentum
Since we don't have the bullet's velocity, we can't directly compare the momentum. However, we can make some observations:
* Mass: The cricket ball is significantly heavier than the bullet.
* Velocity: Even though the cricket ball is moving slower than a typical bullet, its greater mass could potentially give it higher momentum.
Conclusion:
Without knowing the bullet's velocity, we can't definitively say which has higher momentum.
* If the bullet's velocity is very high (much higher than 25 m/s), it would likely have higher momentum despite its smaller mass.
* If the bullet's velocity is relatively low, the cricket ball could have higher momentum due to its much greater mass.
