Mark the correct statement(s).
P
(1) If speed of a body is varying, its velocity must
W be varying and it must have zero acceleration
(2) If velocity of a body is varying, its speed must be varying
(3) A body moving with varying velocity may have constant speed
(4) A body moving with varying speed may have constant velocity if its direction of motion remains constant.
