Answer:
A. 0.806 kN
B. 0.303 kN
Explanation:
<h3>A.</h3>
The kinetic energy of the ball is ...
KE = 1/2mv² = 1/2(0.206 kg)(18 m/s)² = 33.372 J
The work required to reduce this to zero over a distance of 4.14 cm is ...
W = Fd
F = W/d = (33.372 J)/(0.0414 m) = 0.806 kN
__
<h3>B.</h3>
When the distance is 11 cm, the force is ...
F = (33.372 J)/(0.11 m) = 0.303 kN
