T = 0.017 s
From the foot to the brain is almost the same as the height. We are not given the height of the woman, but to find "about" how much time, we need a height to work with.
She *could* be 1.7 m <- height = distance
Formula for speed, where k = speed, d = distance, t = time
k = d/t
Rearrange to solve for time:
t = d/k
Substitute known values:
t = (1.7 m) / (100 m/s)
Solve:
t = 0.017 s
Therefore, it takes about 0.017s for the impulse to travel from the foot to the brain.
Answer:
Theres no way i can walk this road alone Well, daddy grabbed my hand and said
Explanation:
What’s the question? I’d isn’t understand explain
The momentum does not change because he is going the same speed just a different way.
Answer:
5080.86m
Explanation:
We will divide the problem in parts 1 and 2, and write the equation of accelerated motion with those numbers, taking the upwards direction as positive. For the first part, we have:
We must consider that it's launched from the ground () and from rest (), with an upwards acceleration that lasts a time t=9.7s.
We calculate then the height achieved in part 1:
And the velocity achieved in part 1:
We do the same for part 2, but now we must consider that the initial height is the one achieved in part 1 () and its initial velocity is the one achieved in part 1 (), now in free fall, which means with a downwards acceleration . For the data we have it's faster to use the formula , where d will be the displacement, or difference between maximum height and starting height of part 2, and the final velocity at maximum height we know must be 0m/s, so we have:
Then, to get , we do:
And we substitute the values:
