Answer:
Explanation:
d = Distance traveled = 40.8 km
s = Speed of jet = 340 m/s
Time is given by
The time taken to complete the journey is .
First we figure out how many seconds that is
9,390,000,000
then divide by 60 to get how many hours that is<span>
</span>
156,500,000
now divide by 24 to get the number of days
6520833 and 1/3
that is how many days it is
PE = mgh₁ - mgh₂= 12.5J
h₁ = ?
h₂ = 0
h₁ = PE / mg = 12.5 / 9.8

The answer is 3.
When a ball is thrown into the air, there is no friction (there's nothing rubbing against it), so the only force acting on the ball is gravity, which aims to pull the ball back down. Since this is the only force, the answer will equal the gravity acting on the ball. Since "weight" is defined as just that (the gravity acting on something), the answer is 3, the magnitude of the rock's weight (or the force of gravity).
