Answer:
When X = 0
Speed = maximum V (max) = ω A
Acceleration = zero a(max) = - ω^2 A
From x = A sin ω t sin = 0 so displacement = zero
V = ω A cos ω t cos = 1 and speed = maximum
a = - A ω^2 sin ω t sin = 0 and acceleration = zero
B. Kinetic
Kinetic energy depends on motion and mass
I’m pretty sure it does most of the time ig
The answer is 2.3. I just answered this question and got it right.
