Gravitational force is directly related to mass and inversely related to distance. So the bigger the masses the greater the forc

e and the greater the distance the smaller the force. According to the model, which sphere has the greatest gravitational attraction to sphere D?

Answer:Well according to the formula :

Fg = G • m1 • m2

__________

r^2

If one were to increase the masses of the objects it will have a direct impact on the gravitational force as well, as it increase the gravitational force. It is directly proportional to mass.

Distance on the other hand is inversely proportional to the gravitational force, basically increasing the distance between two objects of substantial mass causes a decrease of attraction or gravitational force between those 2 bodies of mass.

A rocket is launched from rest and moves in a straight line at 30.0 degrees above the horizontal with an acceleration of 35.0 m/
klemol [59]

Answer:

t = 123.59s

Explanation:

For the launch pad section:

Vf = Vo + a*t  where Vo=0.

Vf = 35*25 = 875m/s

The distance traveled during the launch:

d = Vo*t+\frac{a*t^2}{2} = 0+\frac{35*25^2}{2} = 10937.5m

Now the projectile motion, we know that its initial speed is the speed calculated previously and the initial height is the y-component of the previously calculated distance.

\Delta Y = Vo*sin(30)*t - \frac{g*t^2}{2}

-d*sin(30) = Vo*sin(30)*t - \frac{g*t^2}{2}  where d= 10937.5m; Vo=875m/s.

Solving for t:

t1 = -11.093s   t2 = 98.59s

So, the total time of flight will be:

t_{total} = t_{launch}+t_{projectile}=25+98.59 = 123.59s

A gun can fire a bullet at 540 m/s. If the gun is aimed at an angle of 55o above the horizontal and fired, what will be the hori
lisabon 2012 [21]

Answer:

Explanation:

The <u>initial</u> vertical velocity is 540sin55° = 442.342103... 442 m/s

The <u>initial</u> horizontal velocity is 540cos55° = 309.731275... 310 m/s

In the real world, both initial velocities would be reduced by air resistance and vertical velocity will be altered by gravity.
