Question

displacement of a particle starts from rest is proportional to square of time,then particle travels with 1.uniform velocity 2.uniform acceleration 3.non uniform speed 4.instantaneous speed

Answer 1

Answer:

Correct option is

2. Uniform acceleration

Explanation:

• The shift of the location of an object is called Displacement.
• It has magnitude as well as direction and therefore it is a vector quantity.
• A vector is depicted by pointing an arrow head towards the destination.

When the velocity change of a body has constant time, the body (object) is said to be in uniform acceleration. That means, the displacement of the body the directly proportional to the square of time in case of uniform acceleration.

Answer 2

The correct option is (2) uniform acceleration.

Given:

If the displacement of an object is proportional to the square of the time taken.

Explanation:

According to Newton's second equation of motion

When the body is moving with uniformly accelerated motion for a particular initial velocity can be written as

$s=u t+\frac{1}{2} a t^{2}$

The equation of motion is only valid for the uniformly accelerated body.

Therefore, when the displacement of a particle is proportional to square of time, then particle travels with uniform acceleration.
