Answer:
t=12600ns
Explanation:
We use the relation between distance and velocity to solve this problem:
d=v*t
d=3.8km=3.8*10^3m
v=3*10^8 m/s^2 light's speed
we solve to find t:
t=d/v=(3.8*10^3)/(3*10^8)=1.26*10^(-5)s=12600*10^(-9)s=12600ns
<u>We are given:</u>
Power of the motor(P)= 95 W
Weight of the object (F)= 120 N
time taken (t)= 6.2 s
Distance covered by the object (s) = s m
<u>Solving for the distance covered:</u>
We are given that the power of the motor = 95 W
we know that <em>power = Work done / Time taken</em>
So, <em>Power = Force * displacement / Time taken </em><em> [Work done = Force * displacement]</em>
replacing the variables
95 = (120 * s) / 6.2
s = 95*6.2 / 120
s = 4.9 m
The equation of the motion of this object is
<h3>What is oscillation?</h3>
An oscillation in a waveform is a periodic set of vibrations an object in the medium produces.
From the parameters given:
- The spring is pulled 3 feet down ward from the origin(equilibrium position) = -3
- Time to complete one oscillation = 4 seconds
The angular velocity can be computed by using the formula:
The amplitude A from the oscillation is:
It implies that the vertical shift (D) is:
However, by using the formula of the general form of a sinusoidal equation, we have:
