8. What average force is needed to accelerate a 7.00-gram pellet from rest to 175 m/s over a distance of 0.700 m along the barrel of a rifle? 9. A fisherman yanks a fish out of the water with an acceleration of 4.5 m/s^2 using very light fishing line that has a "test" value of 22 N. The fisherman unfortunately loses the fish as the line snaps. What can you say about the mass of the fish? 10. A 0.140-kg baseball traveling 45.0 m/s strikes the catcher's mitt, which, in bringing the ball to rest, recoils backward 11.0 cm. What was the average force applied by the ball on the glove?3 I tried doing number 8 on my own. vfinal^2=vinitial^2 + 2ad 175m/s=0^2 + 2a(0.700m) a= 125m/s F=ma F=(7.00g)(125 m/s) F=875N Is this correct>? How do you do the others?
