An estimated force-time curve for a baseball struck by a bat is shown in Figure. From this curve, the magnitude of the impulse (in kg m/s) delivered to the ball if Fmay = 24000N. F (N) F (ms) 24 O b. 21 Oc. 15 O d. 18
Concept Investigation: Impulse and Momentum In the first trial of an experiment, an egg is rolled toward a wall. It bounced back at a certain angle. Since it is rolled toward the hard surface of the wall, it is more likely to obtain damage. On the other hand, the second trial had an egg rolled toward a wall with cushion wrap. As a result, the damaging effect of the impact force is reduced. It also bounced back lesser than the first egg. Why did it happen that way? Kindly explain and elaborate the reason behind it by applying the concept of impulse/momentum/collision/newton's law (anything that will accurately explain the physics behind the results of the experiment). Please help me understand clearly. Thank you so much.
