Air is the example of mixture
Answer:
option D
Explanation:
given,
mass of the rifle,M = 2 Kg
mass of the bullet , m = 0.01 Kg
speed of the bullet, v = 200 m/s
recoil velocity ,v'= ?
initial velocity of bullet and rifle is zero.
using conservation of energy
Mu + m u' = M v'+ m v
0 + 0 = 2 x v' + 0.01 x 200
2 v' = -2
v' = -1 m/s
negative sign represent the velocity of rifle is in opposite direction of bullet.
hence, the correct answer is option D
