I am reviewing for the AP Calc test and I came across this very confusing a challenging problem (confusing to me but maybe not to you). Please explain how to get the answer thanks.
is the (position) vector xi + yj from the origin to a moving point P(x,y) at time t.
a. a single equation in x and y for the path of the point is:
b. when t= 3, the speed of the particle is?
c. The magnitude of the acceleration when t=3 is?
d. at the point where , the slope of the curve along which the particle moves is?
