Answer:
According to the Conservation of Momentum,
Momentum of the gun = momentum of the bullet
M(gun)×V(gun)=m(bullet)×v(bullet)
4kg × V = 0.3kg × 600m/s²
V = (0.3 × 600)/4 = 45 m/s
The recoil velocity on the gun is <em><u>45 m/s</u></em>
<h3><u>45 m/s</u> is the right answer.</h3>
Its mass and net force acting on it
Answer:
heat
Explanation:
because heat the other of transferring energy
A) The acceleration of this car is zero
Because, the question states that it is traveling at a constant velocity, meaning that it has no acceleration at all.
Answer:
Negitive
Explanation:
Electrons have a negitive charge, protons have a positive charge, and neutrons have no charge.
