Answer:
Let's define t = 0 as the moment when the ball hits the wall.
in this moment, we have a given acceleration, but if we only want to calculate the average acceleration, then let's consider the acceleration constant.
a(t) = A.
To find the velocity equation we should integrate, and the constant of integration will be the initial velocity, in this case, is 14.3m/s.
v(t) = A*t + 14.3m/s
Now we know that at t = 0.011s, the velocity is -13.5m/s (the sign is negative because the ball is moving in the opposite direction as before).
Then we can solve the equation:
v(0.011s) = -13.5m/s = A*0.011s + 14.3m/s
Now we can solve it for A, the average acceleration:
-13.5m/s - 14.3m/s = A*0.011s
(-27.8m/s)/0.011s = A = -1313.5 m/s^2
If the particle is not moving relative to the field, the force is 0
I don’t understand what you’re asking, but to find the mean (average), you just add the numbers together, and then divide it by how ever many numbers you added.
For example, to find the average of 1, 1, 5, and 9, first you would add them, which is 16. Then, divide 16 by 4, since there are 4 numbers that were added.
Hope this helps!
