Answer:x=2 and x=3
Explanation:
Given
Potential Energy for a certain mass is
and we know force is given by
For Force to be zero F=0
Therefore at x=2 and x=3 Force on particle is zero.
Answer:
Explanation:
From the question we are told that:
Mass
Speed
Mass
Speed
Generally the equation for Magnitude of the Third piece is mathematically given by
Where
And
Therefore
Answer:
3.2 m/s²
Explanation:
Acceleration can be calculated as:
v = u + at (where v is final velocity, u is initial velocity, a is acceleration and t is time)
25 m/s = 9 m/s + a(5 s) (a is unknown)
16 m/s = a(5 s)
a = 3.2 m/s²
We assume that this is a uniform acceleration (meaning that the velocity increases at an equal rate for those 5 seconds).

<em>Hi there ! </em>
<em>d = m/V => m = d×V</em>
<em>V = l×w×h = 10m×12m×4m = 480 m³</em>
<em>m = 1.26kg/m³×480m³ = 604.8 kg</em>
<em>Good luck !</em>
Frequency = (speed) / (wavelength) = 20 / 0.5 = 40 per second = 40 Hz.
