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.
15 N = 15 kg m / s² =
= 15 · 1/14.59 slug · 1 / 0.3048 =
= 15 · 0.06854 · 3.24254 =
= 3.33 lb
Answer: 15 N is equal to 3.33 pounds.

Explanation:
Answer:
The translational kinetic energy is 225 J
The rotational kinetic energy is 225 J
Explanation:
Given;
mass of the wheel, m = 2-kg
linear speed of the wheel, v = 15 m/s
Transnational kinetic energy is calculated as;
E = ¹/₂MV²
where;
M is mass of the moving object
V is the velocity of the object
E = ¹/₂ x 2 x (15)²
E = 225 J
Rotational kinetic energy is calculated as;
E = ¹/₂Iω²
where;
I is moment of inertia
ω is angular velocity

E = ¹/₂ x 2 x (15)²
E = 225 J
Thus, the translational kinetic energy is equal to rotational kinetic energy
Answer:
Explanation:
Let the height of the tree is y and the distance of tree from point B is x.
According to the diagram

x = 0.55 y ..... (1)

(50 + 0.55y) 1.17 = y ..... from equation (1)
58.5 + 0.644 y = y
0.356 y = 58.5
y = 164.3 ft
