Question

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

when a boby is at highest point of its motion,the velocity of the body becomes zero.but it still excelates with a constant acceleration,which is equal to the acceleration due to gravity,thus this is possible for a body to have zero,velocity and a constant acceleration.........rest would be done similarly .......plzzz mark me as brainlist..............pllzzzzzzzzzz mark me as brainlist........plzzzz mark me as brainlist

Answer 2

Answer:

(a) The above given situation is possible. For example, 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.

(c) The above given situation can be seen in the following example:

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