It depends how the sound travels and the conditions, The speed of sound in dry air, 20°C is 323 m/s
Answer:
8m/s
Explanation:
Sonic can go WAAAAAAAAAAAAY faster, but he must be taking a jog. All jokes aside, Divide 40 by 5. You get 8 meters per second or 17.9 mph.
Answer:
V=1.19m/s
Explanation:
A 30-06 caliber hunting rifle fires a bullet of mass 0.018 kg with a velocity of 417 m/s to the right. The rifle has a mass of 6.29 kg. What is the recoil speed of the rifle as the bullet leaves the rifle?
this momentum.
it has to deal with the interaction between bullet and a gun
.lets have a deep dive into the solution
momentum is the product of mass of a body and the velocity
momentum of the bullet-=momentum of the gun
mv=MV
mass of bullet=0.018kg
v=velocity of bullet
M=mass of rifle 6.29kg
V=recoil velocity of the rifle gun
0.018*417=6.29*V
V=1.19m/s
mass is the quantity of matter in a body
velocity is change in displacement per time
Answer:
Explanation:
Given the absence of non-conservative force, the motion of the coin is modelled after the Principle of Energy Conservation solely.
The moment of inertia of the coin is:
