The answer is "156.6 m/s".
This is how we calculate this;
-N + mg = ma = mv²/r
For "weightlessness" N = 0, so
0 = mg - mv²/r
g - v²/r = 0
v =√( gr)
g = 9.8 and r = 2.5km = 2500 m
v = √(9.8 x 2500)
= 156.6 m/s
Answer:
Depends on how long the string is, how heavy the weight, and how high you let go of it.
But it will most likely hit you :)
hello! it is velocity.
i say this because, Inertia is the tendency of an object to resist changes in its state of motion. ... The state of motion of an object is defined by its velocity - the speed with a direction.
Answer:
2. displacement is maximum
Explanation:
This makes sense as the spring is stretched the farthest at this point
F = kx
The largest force makes the largest acceleration.
