Answer:

 Recoil velocity of cannon = 2.92 m/s

Explanation:

By law of conservation of momentum, we have momentum of cannon = momentum of cannonball.

 Mass of cannon = 1200 kg

Mass of cannon ball = 100 kg

Velocity of cannon ball = 35 m/s

 We have, Momentum of cannon = momentum of cannon ball

                  1200 x v = 100 x 35

                            v =3500/1200 = 2.92 m/s

 Recoil velocity of cannon = 2.92 m/s

What's the process?
Natalka [10]

Answer:

Explanation:

Falling objects form an interesting class of motion problems. For example, we can estimate the depth of a vertical mine shaft by dropping a rock into it and listening for the rock to hit the bottom. By applying the kinematics developed so far to falling objects, we can examine some interesting situations and learn much about gravity in the process.

What did Rutherford’s model of the atom include that Thomson’s model did not have?
Leona [35]
Rutherford tested Thomson'shypothesis by devising his "gold foil" experiment. Rutherford was forced to discard the Plum Pudding modeland reasoned that the only way the alpha particles could be deflected backwards was if most of the mass in an atom was concentrated in a nucleus.
