That's the cool thing about free fall.  The amount of time it takes to fall remains the same.

In this case, a ball that is simply dropped from rest will fall at the same rate as a ball that had some umph in the horizontal direction.

2. A stone is thrown vertically upward with a speed of 22m/s.
Eduardwww [97]

Answer:

Explanation:

Energy E is conserved:

E=\frac{1}{2}mv^2+mgh

If v₀ = 22m/s, h₀=0m and h₁=25m:

E=\frac{1}{2}mv_0^2=\frac{1}{2}mv_1^2+mgh_1

Solving for v₁:

v_1=\sqrt{v_0^2-2gh_1}

There is no real solution, because the stone never reaches 25m.

If you were to drive an average velocity of 65 mi/hr to Traverse City, which is
Amanda [17]
Find the number of hours by dividing the distance by mph. The number of hours will be to the left of the decimal point:

250 miles / 65 mph
= 3.846153846
= 3 hours

2) Find the number of minutes by multiplying what is remaining from step 1 by 60 minutes. The minutes will be to the left of the decimal point:

0.846153846 x 60
= 50.76923076
= 50 minutes

3) Find the number of seconds by multiplying what is remaining from step 2 by 60 seconds. The seconds will be to the left of the decimal point:

0.76923076 x 60
= 46.1538456
= 46 seconds

So 3 hours 50 mins and 46 seconds

In some areas, farmers have installed windmills to generate electricity to run the farm.
Aleks [24]

Answer:

Number 3

Explanation:

Unlike other numbers, this states that wind is "renewable". The choice 2 sounds a bit selfish, or not worded properly, I believe choice 3 is the answer. However, you are the judge of choosing to believe this or not.

Good luck!
