Question

The distance travelled by a particle is proportional to the squares of time, then the particle travels with

• A. Uniform acceleration
• B. Uniform velocity
• C. Increasing acceleration
• D. Decreasing velocity

Answer 1

Answer: (A)

Uniform acceleration

Answer 2

$s \propto t ^ { 2 }$ (given) $\therefore$ $s = K t ^ { 2 }$

Acceleration $a = \frac { d ^ { 2 } s } { d t ^ { 2 } } = 2 k$ (constant)

It means the particle travels with uniform acceleration.
