Which of the following statements is True?
a. A body is moving such that its equation of motion is
represented by v = -3t is an example of constant velocity
motion.
O b. During an interval of time, a particle's average acceleration
is negative. In the same interval, its displacement can be
positive or negative.
O c. A helicopter is going up with constant velocity. Its
acceleration is acceleration due to gravity at that place.
O d. Equation x =x,+at is used when the particle travels with
constant acceleration.
