velocity?

(b) A particle moves over three quarters of a circle of radius r. What is the magnitude of its

displacement?

Answer 1

a) uniform acceleration motion in motion in which the body moves with the same time and distance
uniform velocity is velocity in which displacement and time are same

Answer 2

if a body moves and its acceleration same at all position. this is called uniform accleration.
