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

Answer:

a

Explanation:

It is possible in the case of the body is moving in a circular path

The body is said to be accelerated as the velocity of the body keeps changing..

so the motion is said to accelerated

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. This situation can be explained by the given graph below

(b) 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.This situation can be explained by the given graph below.
