1.	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 in a certain direction with an acceleration in the perpendicular direction.
Answer» (a) Possible When a ball is thrown up at maximum height, it has zero velocity, although it will have constant acceleration due to gravity, which is equal to 9.8 m/s². (b) Possible When a car is moving in a circular track, its acceleration is perpendicular to its direction.

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 in a certain direction with an acceleration in the perpendicular direction.

Answer»

(a) Possible

When a ball is thrown up at maximum height, it has zero velocity, although it will have constant acceleration due to gravity, which is equal to 9.8 m/s².

(b) Possible

When a car is moving in a circular track, its acceleration is perpendicular to its direction.
