Calculation of Acceleration for the Black Ram

To calculate the acceleration of the black ram after it delivers a head-on collision to the white ram, we can use the principle of conservation of momentum. According to this principle, the total momentum before the collision is equal to the total momentum after the collision.

The momentum of an object is given by the product of its mass and velocity. Since the rams are colliding head-on, their velocities are equal in magnitude but opposite in direction. Let's assume the velocity of both rams before the collision is denoted by 'v'.

The momentum before the collision can be calculated as follows:

Momentum before collision = (mass of black ram) * (velocity of black ram) + (mass of white ram) * (velocity of white ram)

Since the rams are initially at rest, the momentum before the collision is zero.

0 = (mass of black ram) * (v) + (mass of white ram) * (-v)

Simplifying the equation, we get:

(mass of black ram) * (v) = (mass of white ram) * (v)

The velocity 'v' cancels out from both sides of the equation, leaving us with:

(mass of black ram) = (mass of white ram)

Therefore, the mass of the black ram is equal to the mass of the white ram.

Now, let's calculate the acceleration of the black ram after the collision. We know that the white ram experiences an acceleration of 2 m/s^2. Since the masses of both rams are equal, the black ram will also experience the same acceleration of 2 m/s^2.

Hence, the black ram will receive an acceleration of 2 m/s^2 after the collision.
