Answer:
153 N
Explanation:
The work done on the ball by the pitcher = Force * distance
[tex]W = F\times d = 1.0 \text{ m} \times F = F[/tex]
The energy of the baseball is kinetic because it moves.
[tex]KE = \frac{1}{2}mv^2[/tex]
[tex]m[/tex] is the mass and [tex]v[/tex] is the velocity.
[tex]KE = \frac{1}{2}0.145\times 46^2 = 153.41 \text{ J}[/tex]
By the work-kinetic energic theorem, [tex]W= KE[/tex]
Hence [tex]F = 153 \text{ N}[/tex]
