Answer:
.
Explanation:
If the mass of an object is
and the velocity of that object is
, the linear momentum of that object would be
.
Assume that the initial velocity of the mass is positive (
.) However, the direction of the velocity is reversed after the impact. Thus, the sign of the new velocity of the object would be negative- the opposite of that of the initial velocity. The new velocity would be
.
Thus, the change in the velocity of the mass would be:
.
The change in the linear momentum of the mass would be:
.
Thus, the magnitude of the change of the linear momentum would be
.
Answer:
Time to get a new fence...?
C'mon that's pretty cringe lol
Please give brainliest
have a nice day :D
Answer:
º
Explanation:
From the exercise we have our initial information

When the balloon gets to the ceiling its velocity at that moment is 0 m/s. Being said that we can calculate velocity at the vertical direction

Since
and 


Knowing that

Answer:
81.9756 m/s
16.8 m
4.8795 Hz
Explanation:
m = Mass of string = 0.12 kg
L = Length of string = 8.4 m
T = Tension on string = 96 N
Linear density is given by

Spee of the wave is given by

The speed of the waves on the string is 81.9756 m/s
Wavelength is given by

The longest possible wavelength is 16.8 m
Frequency is given by

The frequency of the wave is 4.8795 Hz
