Answer:
Explanation:
As per Heisenberg's uncertainty principle we know that
so here we have
now from above equation we have
Answer:
Explanation:
To determine the <u>muzzle velocity of the gun</u>, we must know how long does it take the ball to <u><em>strikes the ground </em></u>
Since the ground is at y=0 and
Solving for t
Now, to determine the muzzle velocity we need to find its acceleration first
(1)
(2)
If we analyze the final velocity is 0. From (2) we have that
(3)
Replacing (3) in (1)
Solving (3)
The impulse is 10 kg m / s.
<u>Explanation:</u>
An impulsive force is a short duration of force. The result of the force acting for the given amount of time is that the object's speed up or slow down of mass. The impulse experienced equals the change in momentum of the object.
Given the mass m = 1.0 kg
The formula is given as,
Impulse = mass ( change in velocity)
= 1.0 ( 10 - 0)
Impulse = 10 kg m /s.
We only need to look at Newton's 2nd law of motion:
Net force = (mass) x (acceleration)
If the net force on an object is zero, then either its mass or its acceleration must be zero. If it's called an "object", then its mass isn't zero, so its acceleration is zero.
