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:

option c is correct

Explanation:

when an object moves with uniform speed then acceleration is perpendicular to y axis or parallel to X axis

hope it helps if yes then mark me as brainliest

Answer 2

Answer:

All the situations are possible

Explanation:

a) Eg:- Vertical particle projection

When an object is thrown upwards, the maximum height velocity of the body is zero, but the constant acceleration due to gravity is still working.

b) Eg:- Circular motion is an example of an object which is moving with acceleration but with uniform speed. ...

In case of circular motion, the velocity keeps changing as direction changes( though magnitude remains constant) and hence the object is accelerated but there's no change in speed( the magnitude).

c) Eg:- Circular motion

When an object is moving along a circular motion its path is along the circle tangent but the centripetal acceleration is towards the circle radius.

We understand that with the radius, a tangent still makes a right angle.

So when the object in a circular motion, the velocity and accelerations are in a mutually perpendicular direction.
