When an object in simple harmonic motion is at its maximum displacement, its <u>acceleration</u> is also at a maximum.
<u><em>Reason</em></u><em>: The speed is zero when the simple harmonic motion is at its maximum displacement, however, the acceleration is the rate of change of velocity. The velocity reverses the direction at that point therefore its rate of change is maximum at that moment. thus the acceleration is at its maximum at this point</em>

Answer:

Explanation:
Given that,
x component of a vector = -12 m
The y component of a vector = -15 m
We need to find the direction of a vector. The direction of a vector is given by :

Put all the values,

So, the direction of vector is
to x component.
Power is defined as
P = I*V
where I is the current and V is the voltage
Ohm's law gives us the relation betwen Voltage and current in a resistive component
V = I*R , Then
P = V² / R
We solve for R,
R = (110 V)²/ 75W = 161.33 ohms
B is the correct answer for sure bro
It is trajectory acceleration. A friction track is a device to study motion in low friction environments, I believe. Does this help?
