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:

C)

Explanation:

• Because acceleration due to gravity will act in perpendicular direction while object is moving forward.
• Also A) is not possible as acceleration involves change in velocity but change in velocity will not take place if velocity is zero.
• Also B) is not possible as change in velocity will not take place if velocity is constant
