State which of the following situations are possible and give an example for each of these: - an object with a constant acceleration but with zero velocity
- an object moving with an acceleration but with uniform speed.
- an object moving in a certain direction with an acceleration in the perpendicular direction.
- an object with a constant acceleration but with zero velocity
- an object moving with an acceleration but with uniform speed.
- an object moving in a certain direction with an acceleration in the perpendicular direction.
Solution and Explanation
(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 \(9.8\) \(m/s^2\).
(b) Possible.
When a car is moving in a circular track, its acceleration is perpendicular to its direction.
(c) Possible.
A car is moving in a circular track, its acceleration is perpendicular to the direction of motion.

Concepts Used:
Speed and Velocity
The rate at which an object covers a certain distance is commonly known as speed.
The rate at which an object changes position in a certain direction is called velocity.
