Answer :
The velocity of the pitcher at the given mass is 0.105 m/s.
The given parameters:
- Mass of the pitcher, m = 50 kg
- Mass of the baseball, m = 0.15 kg
- Velocity of the ball, v = 35 m/s
The velocity of the pitcher is calculated by applying the principle of conservation of linear momentum as follows;
[tex]m_pv_p = m_bv_b\\\\v_p = \frac{m_bv_b}{m_p} \\\\v_p = \frac{0.15 \times 35}{50} \\\\v_p = 0.105 \ m/s[/tex]
Thus, the velocity of the pitcher at the given mass is 0.105 m/s.
