The muzzle velocity of a rifle bullet is 709 m s−1along the direction of motion. if the bullet weighs 35 g, and the uncertainty in its momentum is 0.20%, how accurately can the position of the bullet be measured along the direction of motion?

Uncertainty in position of the bullet is

Explanation:

It is given that,

Mass of the bullet, m = 35 g = 0.035 kg

Velocity of bullet, v = 709 m/s

The uncertainty in momentum is 0.20%. The momentum of the bullet is given by :

Uncertainty in momentum is,

We need to find the uncertainty in position. It can be calculated using Heisenberg uncertainty principal as :

Hence, this is the required solution.

f=ma newton

f=100x2.5=250n
