Answer:
Distance of the second child from the pivot point will be 2.66 m
Explanation:
We have given mass of the first child
Distance from the pivot point
Mass of the second child
We have to find the distance of the second child from the pivot point
For this we have to balance the moment
So
So the distance of the second child from the pivot point point will be 2.66 m

Answer:
22.5 [m] is the distance from the person to the second post.
Explanation:
We can solve this problem graphically, first place the position of the person at the origin of x-y coordinates.
Then we locate the first post (1), tracing a line (or vector) with a length of 52 [m] from the origin of coordinates and with an angle of 37 ° north of East.
And for finding the distance from the second post (2) with respect to the person, we have to draw a line that has a length of 68 [m] and this line must be crossed with the y-axis and in the negative direction, in this way we can find the distance from the post with respect to the person.
Note: we can use set square and protractor to solve this problem
In the attached image we can find the graphic solution.
By this method of construction we can find the distance of post number 2 from the person and this is 22.55 [m] to the South
Heya!!
For calculate final velocity, lets applicate formula
<u>Δ Being Δ</u>
V = Final Velocity = ?
Vo = Initial velocity = 0 m/s
a = Aceleration = 5 m/s²
t = Time = 12 s
⇒ Let's replace according the formula:
⇒ Resolving
Result:
The velocity after 10 sec is <u>60 meters per second (m/s)</u>
Good Luck!!
