Question
The curve on the left represents an object in simple harmonic motion. Match the points on the curve to the velocity and acceleration of the object.
Point A Point B Point C Point D Point E Point F Point G Point H The velocity is negative, and the acceleration is positive.
Point A Point B Point C Point D Point E Point F Point G Point H The velocity is zero, and the acceleration is negative.
Point A Point B Point C Point D Point E Point F Point G Point H The velocity is zero, and the acceleration is positive.
Point A Point B Point C Point D Point E Point F Point G Point H The velocity is positive, and the acceleration is zero.
Explanation / Answer
x=Acoswt
v=x'=-Awsinwt
a=x''=-Aw^2coswt
A-0<wt</2-so v<0 and a<0
B-wt=/2-so v<0 and a=0
C-/2<wt<-so v<0 and a>0
D-wt=-so v=0 and a>0
E-<wt<3/2-so v>0 and a>0
F-wt=3/2-so v>0 and a=0
G-3/2<wt<2-so v>0 and a<0
H-wt=2-so v=0 and a<0
