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

Answer:

a......it is possible

as when we throw an object vertically upwards...at the highest point the v is 0 but acceleration that is9.8 is constant

b.....it is possible

in case of uniform circular motion

c.....its possible .. in case of projectile motion...as we throw an object....it is moving in certain direction but its acceleration is perpendicular downwards....is g
