Question

9. State which of the following situations are possible and give
an example for each of these:
(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

a) Not possible

b) Yes,when the object is in circular motion.

c) Yes,when we throw a ball in the upward direction, gravity acts constantly in the opposite direction.

For perpendicular direction, throwing a ball makes it fall down as gravity acts in the perpendicular direction.

Hope it helps
