The model of the atom evolved as scientists have made new discoveries.</span>
It’s e 2.0 x 10^-4 because it is a fraction
The velocity of the pitcher at the given mass is 0.1 m/s.
The given parameters:
- <em>Mass of the pitcher, m₁ = 50 kg</em>
- <em>Mass of the baseball, m₂ = 0.15 kg</em>
- <em>Velocity of the ball, u₂ = 35 m/s</em>
<em />
Let the velocity of the pitcher = u₁
Apply the principle of conservation of linear momentum to determine the velocity of the pitcher as shown below;
m₁u₁ = m₂u₂

Thus, the velocity of the pitcher at the given mass is 0.1 m/s.

The answer is Hypothesis because she can predict that she needs a bigger bag
I would have to say B failed because I think I read something about it being only 2law not 3
