Answer:
x=±0.026m
Explanation:
In simple harmonic motion the maximum value of the magnitude of velocity
The speed as a function of position for simple harmonic oscillator is given by
where A is amplitude of motion
Given data
Amplitude A=3 cm =0.03 m
v=(1/2)Vmax
To find
We have asked to find position x does its speed equal half of is maximum speed
Solution
The speed of the particle the maximum speed as:
x=±(√3(0.03)/2)
x=±0.026m
Toooo much XDD(just a joke) but the real answer is 18.5
Answer:
C
Explanation:
because it not running will set it off course but running all the time it will run. out of fuel
Answer:
a) t = 9.16*10^{-18} s
b) y = 0.402 mm
Explanation:
(a) To find the time that the particle takes to pass trough the region between parallel plates, you take into account that the horizontal component of the velocity is constant in all trajectory of the particle. Then, you use the following formula:
x: length of the sides of the plates = 0.22m
v_x: horizontal component of the velocity = 2.4*10^6 m/s
(b) To find the vertical displacement of the particle you first calculate the acceleration of the particle generated by the electric force:
where you have used that the charge is 1.6*10^-19 C (charge of an electron).
With the values of the acceleration and time you use the following kinematic equation to calculate the vertical displacement:
