Answer:
The least effective answer would be "It's okay to lose control every once in a while."
Explanation:
This answer would make it seem like you are either already on drugs or you are willing to try them, which i assume in this case, you are not.
Let's write the equations of motion on both x- (horizontal) and y- (vertical) axis. On the x-axis, it's a uniform motion with constant velocity vx. On the y-axis, it is a uniformly accelerated motion with initial height h=90 m and acceleration of

pointing down (so with a negative sign):


First, let's find the time at which the jumper reaches the ground. This happens when Sy(t)=0:

and so

Then, we can find the horizontal speed. In fact, we know that at the time t=4.28 s, when the jumper reached the ground, he covered exactly 180 m, so Sx=180 m. Using this into the law of motion in x, we find
Answer:
weakens by 64 times
Explanation:
According to universal law of gravitation the force between two bodies is inversely proportional to square of their distance between them that F is inversely proportional to
So if we increase the the distance between two planets by 8 times then the the mutual attraction between will be decrease by
times
Answer:
The boiling point of Acetone is 329K (in 3 significant figures)
Explanation:
Boiling point of Acetone = 56°C = 56 + 273K = 329K (in 3 significant figures)
