Answer:
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.
Answer:
F = 53153.36[N]
Explanation:
In order to solve this problem, we must first use the principle of conservation of energy which is transformed from potential energy to kinetic, in this way we can determine the velocity at which the person enters the water.
where:
m = mass = 100 [kg]
g = gravity acceleration = 9.81 [m/s²]
h = elevation = 9 [m]
v = velocity [m/s]
Now replacing we can determinate the velocity.
Then we can calculate the momentum which can be calculated as the product of force by time, this momentum is also equal to the product of mass by velocity.
Now replacing:
F = impact force [N]
t = time = 0.025 [s]
m = 100 [kg]
v = velocity = 13.28 [m/s]
