Question

(a) If the displacement of an object is proportional to square of time, then the object moves with:
(i) Uniform velocity
(ii) Uniform acceleration
(iii) Increasing acceleration
(iv) Decreasing acceleration ​

Answer 1

Answer:

(ii) Uniform acceleration

Explanation:

Figure it up by urself.

Answer 2

Answer:

ii) Uniform acceleration

Explanation:

distance ∝ (time)²

Velocity = displacement

                        time

∴Velocity ∝ time

acceleration: Change in velocity =  v - u

                                 time                     t

∴Acceleration ∝ time⁰

                              ↓

                               1

Acceleration : uniform
