V0=0 S1=40 см S2=20 см mгр= 2 кг mт—?

To solve this problem, we can use the equation for average velocity, which is given by:

v = (Δs/Δt)

Given that V0 = 0, we can assume that the initial velocity is also 0.

We have two displacements: S1 = 40 cm and S2 = 20 cm. To find the total displacement (Δs) during the time interval (Δt), we can add the two displacements together:

Δs = S1 + S2 Δs = 40 cm + 20 cm Δs = 60 cm

Now, we need to find the time interval (Δt) during which the displacements occurred. But we are not given any information about time, so we cannot calculate Δt.

Therefore, we cannot determine the average velocity (v) and we cannot calculate the final mass (mт).
