Answer:
<em>12 m/s</em>
Explanation:
<u>Projectile Motion</u>
It's also known as 2D motion because the movement takes place in both axis x and y. The x-axis motion is at a constant speed since in absence of friction, no external force stops or accelerates the object. The y-axis motion is at variable speed, which is changed by the acceleration of gravity that makes the object to reach a maximum height and then go back to ground level.
The maximum horizontal distance reached (also called Range) is given by
Knowing that 
, we solve for Vo
Thus, the initial speed of Mike Powell was 12 m/s
Calculate the length of a spaceship as follows:
l = l₀√1 - v²/c²
=(400 m)√1 - (0.75c)2 c²
=264.575m.

Answer:
If a negatively charged balloon is brought near one end of the rod but not in direct contact, then <u>the negative charges on the balloon repel the same amount of negative charges on the end of the rod that is close to the balloon</u>, and the positive charges stay at the balloon-side of the rod. The total charge of the rod is still zero, but the distribution of the charges are now non-uniform.
