GPE=mgh, where m=mass, g=acceleration due to gravity, h=height
We have a force of 675N already, so mg=675N
<span>GPE=mgh=675(26000)=17.55x10^6J</span>
Answer:
Explanation:
Volume of cube=side³
=2*2*2
=8 cm³
Mass of cube=40g
Its density=mass/volume
=5g/cm³
which differs the value given in the text hence it is not gold and u should not bye it...
Instead u should call the police for arresting the person lol...
Answer:
The time is 0.90 sec.
Explanation:
Given that,
Height = 4.00 m
We need to calculate the time
Using equation of motion

For free fall, u = 0

Where, s = distance
g = acceleration due to gravity
t = time
Put the value into the formula


Hence, The time is 0.90 sec.
they have zero momentum before pushing off, is at least true
Is drifting around in space
