Answer:

F=35651.04N

Explanation:

Let's start writing all the data from the question.

We have the mass ''m'' of the cannonball :

m=7.5kg

We have the final speed ''Vf'' of the cannonball :

Vf=185\frac{m}{s}

And we have '' Δx '' which is the total distance that the cannonball travelled inside the cannon muzzle :

Δx = 3.6m

If we want to find the average net force applied to the ball, we need to find the acceleration of the cannonball (because we already have the mass of the cannonball).

We can use the following equation in order to find the acceleration :

Vf^{2}=Vi^{2}+2.a.Δx (I)

Where ''Vi'' is the initial speed.

Where ''a'' is the acceleration

If we replace all the data in the equation (I) (And assuming Vi=0 because that is the initial speed of the cannonball before the cannon is shot) :

(185\frac{m}{s})^{2}=0^{2}+2.a.(3.6m)

a=\frac{34225\frac{m^{2}}{s^{2}}}{(2).(3.6m)}=4753.47\frac{m}{s^{2}}

a=4753.47\frac{m}{s^{2}}

Now, we can use the Newton's second law of motion to find the force ''F''

F=m.a

F=(7.5kg).(4753.47\frac{m}{s^{2}})

F=35651.04N

Where ''N'' is the unit Newton a force unit.

We find that the average net force applied to the ball is F=35651.04N

The mass of a carbon atom is 12. 00amu while the mass of a helium-4 atom is 4. 003amu. If three atoms of helium fuse to form car
Naily [24]

If three atoms of helium fuse to form carbon than 0.009 u of mass is converted into energy

Given: m(He) = 4.003 u

and m(C) = 12.000 u

Mass of 3 alpha particles =3×4.003 u

                                       =12.009 u.

Mass of 1 carbon atom=12.000 u

Mass Defect =△m=12.009−12.000=0.009 u

Energy released =0.009×931.5=8.3835 MeV.

So, 0.009 u of mass is converted into 8.38 Mev energy.

omeli [17]
During the period of constant acceleration, the car's average speed is (1/2) (16 + 32) = 24 m/s. At that average speed, it covers 240 meters in 10 seconds.
