Answer 2

To find the mass (m2) of the second object (m2) in the given scenario, we can use the principle of conservation of momentum. According to this principle, the total momentum before an event is equal to the total momentum after the event, provided no external forces act on the system.

The formula for momentum is:

Momentum (p) = mass (m) * velocity (v)

Given: V1 = 3 m/s (velocity of the first object) V2 = 4 m/s (velocity of the second object) m1 = 40 kg (mass of the first object)

We can set up the conservation of momentum equation as follows:

m1 * V1 = m2 * V2

Now, we can solve for m2:

m2 = (m1 * V1) / V2 m2 = (40 kg * 3 m/s) / 4 m/s m2 = 120 kg / 4 m/s m2 = 30 kg

So, the mass of the second object (m2) is 30 kilograms.
