Answer:
<em>The force between the ball and the bat = 2233 N</em>
Explanation:
Force: This can be defined as the product of force and its acceleration.
The S.I unit of Force is Newton (N)
F = ma .............................. Equation 1
Where F = Force , m = mass of the ball, a = acceleration of the ball.
where
a = (v-u)/t..................... Equation 2
Where v = final velocity of the ball, u = initial velocity of the ball, t = time of contact between the ball an the bat.
<em>Given: v = 46 m/s u = - 31 m/s (it hit an horizontal line drive back at the pitcher), t = 5×10⁻³ s</em>
<em>Substituting these values into equation 2,</em>
<em>a = [46-(31)]/(5×10⁻³ )</em>
a = 77<em>×10³/5</em>
<em>a = 15.4×10³ m/s².</em>
<em>Also given m = 0.145 kg</em>
<em>Substituting into equation 1,</em>
F = 0.145(15.4<em>×10³ )</em>
F = 2233 N
<em>Thus the force between the ball and the bat = 2233 N</em>
