Answer:
<h2>39.2 m</h2>
Explanation:
The height of the hill side can be found by using the formula
p is the potential energy
m is the mass
From the question we have
We have the final answer as
<h3>39.2 m</h3>
Hope this helps you
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:
Increases with increase in mass
Explanation:
gravity is proportional to mass and inversely proportional to the square of the distance between them
F = GMm/d²
