I don't know what you mean when you say he "jobs" the other ball, and the answer to this question really depends on that word.
I'm going to say that the second player is holding the second ball, and he just opens his fingers and lets the ball <u><em>drop</em></u>, at the same time and from the same height as the first ball.
Now I'll go ahead and answer the question that I've just invented:
Strange as it may seem, <em>both</em> balls hit the ground at the <em>same time</em> ... the one that's thrown AND the one that's dropped. The horizontal speed of the thrown ball has no effect on its vertical acceleration, so both balls experience the same vertical behavior.
And here's another example of the exact same thing:
Say you shoot a bullet straight out of a horizontal rifle barrel, AND somebody else <em>drops</em> another bullet at exactly the same time, from a point right next to the end of the rifle barrel. I know this is hard to believe, but both of those bullets hit the ground at the same time too, just like the baseballs ... the bullet that's shot out of the rifle and the one that's dropped from the end of the barrel.
Answer:
b) 3.72m/s²
c) 9.33*10^5
d) 9.33*10^5
e) 11.85 hrs
Explanation:
a) to confirm that gEarth is about 98 m/s².
Let's use the formula:
= 9.78 m/s²
=> 9.8m/s²
b) Given:
r = 2106 miles
=3.72 m/s²
c) we use:
d) Let's take the force of gravitybon earth due to satellite as our answer in (c) because the Earth's gravitational force on a GPS satellite and the force of gravity on a GPS satellite on earth are equal and opposite (two mutual forces).
e) In a circular motion,
Gravitional force = Centripetal force.
Solving for v, we have
v = 3886m/s
Therefore,
v = 2πR/T
Solving for T, we have:
T = 42650seconds
Convert T to hours
T = 42650/60*60
T = 11.86hrs
Answer:
1.67×10^-11 N
Explanation:
m1 = 0.13kg
m2 = 0.34kg
d = 0.42m
G = 6.674 × 10 ^−11
F = Gm1m2/r²
F= (6.674 × 10^ −11×0.13×0.34)/(0.42)²
F = 1.67×10^-11 N
Do you mean ‘Does a larger object have less attraction than a smaller object?’ If so, then the answer is objects with a larger mass exert more attraction while objects with a smaller mass have less attraction.
There are three factors:
The charge of the two objects. The electric force is proporcional to the product of the charges of both objects.
The distance that separetes them. The electric force is proportional to the inverse of the squared distance that separates the objects.
The media. The electric force constant of proportionality depends on the media: air, water, oil, glass.
