Question

car?
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 in a certain direction with an acceleration
in the perpendicular direction.​

Answer 1

Answer:

(a) possible

Explanation:

when a ball is thrown vertically upwards,at the highest point ,its velocity is zero. But has a constant acceleration of 9.8 m/s square in the vertically downward direction

(b) possible

when a car is moving at a constant speed on a circular track, it has an acceleration perpendicular to its direction of motion (in radical direction)
