1. The problem
The answer is A.
x = Acoswt
y = Asinwt
C is not correct because the x & y positions are in terms of sin & cos, so the acceleration can't be constant.
D is not correct because x & y are oscillating in value.
E is not correct because y is changing with time
Therefore it's either A or B, which makes sense since x & y are oscillating, they have to form some sort of circle.
I'm stuck between A & B. How do you know the particle is moving with constant speed? B/c the acceleration is definitely not 0. In fact, how do you know these 2 functions describe a circle?
The answer is A.
