(a) an object with a constant acceleration but with zero velocity
b) an object moving with an acceleration but with uniform speed.
(c) an object moving in a certain direction with an
acceleration in the perpendicular direction.​

Answer 1

Answer:

a) it is not possible because a object can move with an acceleration so it will have some velocity

b)this situation is possible,example we can accelerate a car but we acceleration it over with a constant acceleration for a time period it will move with uniform speed.

c)this situation is also possible, example is opening and closing of door , this effect is called torque
