A particle moves on a line according to the law

s = a{t^2} + bt + c

. If the displacement after 1 sec is 16 cm, the velocity after 2 sec is 24 cm/sec and acceleration is

8\mathrm{cm}/{\sec ^2}\mathrm{\;}

⁡ , then

View answer and explanation

Correct option: A

a = 4,\;b = 8,\;c = 4

Option A (

a = 4,\;b = 8,\;c = 4

) is correct because these values satisfy the given conditions for displacement, velocity, and acceleration.
