Answer:
1. Speed=0
2. 2.46 s
3.30.1 m
4. 22.0 m
5.1.004 s
Explanation:
We are given that
Initial speed of blue ball, u=24.1 m/s
Height of blue ball from ground y_0=0.5 m
Initial speed of red ball , u'=7.2 m/s
Height of red from ground=y'0=32 m
Gravity, g=
1.When the ball reaches its maximum height then the speed of the blue ball is zero.
2.v=0
Using the formula and substitute the values
Where g is negative because motion of ball is against gravity
3.
Using the formula
4.Time of flight for red ball=3.77-2.9=0.87s
Hence, the height of red ball 3.77 s after the blue ball is 22.0 m.
5.According to question
Hence, 1.004 s after the blue ball is thrown are the two balls in the air at the same height.
'D' would do the job ... When you subtract the protons from the mass,
what you have left is neutrons. (The electrons can be ignored. It takes
around 1840 electrons ! to add the mass of a single proton or neutron !)
I don't know it for a fact, but I'd be surprised if the process is really that
simple. I mean, it starts out with knowing the atomic mass, and then
knowing the number of protons in the nucleus. Each of those is a
whole complex problem in itself.
Answer:
Hey
Your answer would be:
stationary objects within the field will move when realesed.
The reason why is because fields store potential energy as you know. when something is stationary it has potential, but when it is released that potential energy turns into kinetic energy.
this made me think of a funny joke:
A man was about to jump off of the Empire State Building when a physicist from below yield, Wait don't! you have so much potential!
lol always cracks me up.
