Multiple Choice
An object is moving to the right in the xy-plane along the curve y =
. At the instant when it is at the point
, its speed is 2 and that speed is decreasing at rate 1. What are the velocity and acceleration of the object at that instant?
A) v = (i + j) , a = (1 +
) i + (1 -
) j
B) v = (i + j) , a = i - j
C) v = 2 (i + j) , a = (1 + ) i + (1 -
) j
D) v = 2 (i + j) , a = -i + j
E) v = (i + j) , a = -i + j
