Calculation of the Mass of Fragments

To calculate the mass of the fragments, we can use the principle of conservation of momentum. According to this principle, the total momentum before the explosion is equal to the total momentum after the explosion.

Given: - Mass of the projectile (initially moving horizontally): 60 kg - Initial velocity of the projectile: 300 m/s - Velocity of the larger fragment (moving in the same direction): 500 m/s - Velocity of the smaller fragment (moving in the opposite direction): -200 m/s (negative sign indicates opposite direction)

Let's assume the mass of the larger fragment is m1 and the mass of the smaller fragment is m2.

Using the conservation of momentum, we can write the equation:

Initial momentum = Final momentum

(mass of the projectile) * (initial velocity of the projectile) = (mass of the larger fragment) * (velocity of the larger fragment) + (mass of the smaller fragment) * (velocity of the smaller fragment)

60 kg * 300 m/s = m1 * 500 m/s + m2 * (-200 m/s)

Now we can solve this equation to find the masses of the fragments.

Solution:

Let's solve the equation using the given values:

60 kg * 300 m/s = m1 * 500 m/s + m2 * (-200 m/s)

18000 kg·m/s = 500 m/s * m1 - 200 m/s * m2

Rearranging the equation:

500 m/s * m1 - 200 m/s * m2 = 18000 kg·m/s

We have one equation with two unknowns, so we need another equation to solve for m1 and m2. Unfortunately, the given information does not provide any additional equations or information to solve for the masses of the fragments.

Therefore, without additional information, we cannot determine the masses of the fragments.

Please provide any additional information or equations if available, and I will be happy to assist you further.
