Verified Answer
A bullet of mass 0.01 kg is fired from a rifle. The bullet takes 0.003...
GIVEN,
MASS OF BULLET(m) = 10G = 10/1000 = 0.01KG
TIME TAKEN(t) = 0.003 SECS.
INITIAL VELOCITY (u) =300 M/S
FINAL VELOCITY (v) = 0.
ACCELERATION (a) =?
FORCE (F) = ?
BY USING 1ST EQUATION OF MOTION,
WE GET,
v = u + at
300 = 0 + a X 0.003
300 = a X 0.003
300/0.003 = a
100,000 = a
OR
a = 100,000 M/S2.
NOW,
WE KNOW THAT,
F = m X a
= 0.01 X 100,000
= 1000 N..

A bullet of mass 0.01 kg is fired from a rifle. The bullet takes 0.003...
Acceleration is defined as the rate of change of velocity with respect to time. It is calculated by dividing the change in velocity by the time taken. In this case, the bullet starts from rest and reaches a velocity of 300 m/s in 0.003 s.
Therefore, the change in velocity is:
Δv = 300 m/s - 0 m/s = 300 m/s
The time taken is given as 0.003 s.
Now, we can use the formula for acceleration:
a = Δv / t
Substituting the values, we get:
a = 300 m/s / 0.003 s = 100,000 m/s^2
So, the acceleration acting on the bullet is 100,000 m/s^2.
Therefore, the correct answer is option 'B'.
Therefore, the change in velocity is:
Δv = 300 m/s - 0 m/s = 300 m/s
The time taken is given as 0.003 s.
Now, we can use the formula for acceleration:
a = Δv / t
Substituting the values, we get:
a = 300 m/s / 0.003 s = 100,000 m/s^2
So, the acceleration acting on the bullet is 100,000 m/s^2.
Therefore, the correct answer is option 'B'.

Mass of bullet =0.01kgTime taken =0.003sV=300m/sAcceleration =v---u/t =300--0/0.003 =300/0.003 =100×1000 =100000m/s square
