To develop this problem it is necessary to apply the concepts related to the Dopler effect.
The equation is defined by
Where
= Approaching velocities
= Receding velocities
c = Speed of sound
v = Emitter speed
And
Therefore using the values given we can find the velocity through,
Assuming the ratio above, we can use any f_h and f_i with the ratio 2.4 to 1
Therefore the cars goes to 145.3m/s
Newton's 2nd law of motion:
Force = (mass) x (acceleration)

(1,500 kg) x (7 m/s²) = 10,500 newtons .
<span>Because of
the density of the paperclip it sinks, but even though a boat is normally made
of steal it contains an opposite force of gravity known as buoyancy. Buoyancy
is the reason that a boat will float. Boat density is less weight than the water
they are in so this is one reason that they are floaters.</span>
Kinetic energy because the ball is in motion or moving with energy behind it... kinda like when you shoot a gun, the bullet is fired out of the muzzle with kinetic energy ( Punch ) and the bullet goes through a wall or something. Sorry but my math skills aren't very good to give complex calculations but I would recommend that you maybe talk to some of the top ranking math guys on the website. Maybe they can give you better help...
Anyways, I hope I have been helpful to you.
