Answer 2

Calculating Change in Velocity

To find the change in velocity of an object with a mass of 4 kg when the change in momentum is 20 Ns, we can use the formula:

Change in momentum (Δp) = mass (m) * change in velocity (Δv)

We can rearrange this formula to solve for the change in velocity:

Δv = Δp / m

Substituting the given values:

Δv = 20 Ns / 4 kg

Calculating the change in velocity:

Δv = 5 m/s

Therefore, the change in velocity of the object with a mass of 4 kg is 5 m/s.
