Yes humans have traveled in space before
Explanation:
Gravitational potential energy
= mgh
= (2kg)(10N/kg)(5m)
= 100J.
I think its d. but im not sure
Answer:
Explanation:
Given:
- Mass of 1st body =

- Mass of 2nd body =

To Find:
- Magnitude of gravitational force
Solution:
Here, we have a formula
<u>Substituting the values</u>




Know More:
The applied formula for the above solution is

where,
- F
= Gravitational force - G = Gravitational constant
- M
= mass of 1st body - M
= mass of 2nd body - r = distance between two bodies
Answer:
Maximum height, h = 10 m
Explanation:
It is given that,
Mass of golf ball, m = 45 g = 0.045 kg
The ball comes down on a tree root and bounces straight up with an initial speed of 14.0 m/s.
We need to find the height the ball will rise after the bounce. It is based on the conservation of energy such that,

h is maximum height raised by the ball

So, the ball will raised to a height of 10 meters.
