The speed of the ball just before impact was v=√(2gh) = 6.26m/s. The acceleration is twice this over the time (twice because the second speed is the same in the other direction, meaning the total change in speed is 2V)
a = 12.52/0.10 = 125.2m/s²
The force is F=ma, so F = 0.5kg·125.2m/s² = 62.6N
Displacement (between time 0 and time 25) is the area under the velocity time curve, i.e. ∫ vdt.
Here, v(0)=10, v(25)=34 (approx.)
Therefore
displacement = (1/2)(10+34 m/s)*(25-0) s [ trapezoid area ]
=550 m
4x time 10x (I think)
Here, this will help-

Grade 3 is a completely torn ligament
Answer:
The answer to your question is: letter D
Explanation:
Fussion: means combine 2 light nucleus to form heavier nucleus.
Fission: means splitting heavy nucleus to form lighter nucleus.
In the figure we can see two light nucleus that combine to form heavier nucleus, so the answer is nuclear fussion.
