A bullet in a gun is accelerated from the firing chamber to the end of the barrel at an average rate of 6.20*10^5 M/s^2 for 8.10*10^-4 s what is its muzzle velocity
v = a t
(6.20*10^5)*(8.10*10-4)=502.2m/s
To find the muzzle velocity of the bullet, we need to use the equation of motion:
v = u + at
Where:
v = final velocity (muzzle velocity)
u = initial velocity (0 m/s as the bullet starts from rest)
a = acceleration
t = time
Given:
a = 6.20 × 10^5 m/s^2
t = 8.10 × 10^-4 s
Substituting these values into the equation of motion:
v = 0 + (6.20 × 10^5 m/s^2) × (8.10 × 10^-4 s)
v = 5.022 × 10^2 m/s
Therefore, the muzzle velocity of the bullet is 5.022 × 10^2 m/s.
To find the muzzle velocity of the bullet, we need to calculate the final velocity of the bullet after it has been accelerated.
We can use the equation of motion:
vf = vi + at
Where:
vf is the final velocity
vi is the initial velocity
a is the acceleration
t is the time
Since the bullet starts from rest (initial velocity, vi = 0), and we know the acceleration (a = 6.20 * 10^5 m/s^2) and the time (t = 8.10 * 10^-4 s), we can plug these values into the equation to find the muzzle velocity:
vf = 0 + (6.20 * 10^5 m/s^2) * (8.10 * 10^-4 s)
vf = 502 m/s
Therefore, the muzzle velocity of the bullet is 502 m/s.
