1. An uniformly accelerated body travels a distance of 24 m in $(5^{\text{th}})$ second of its motion and 44 m in $(15^{\text{th}})$ sec of its motion. The acceleration of the particle will be
(1) $(1 m / s^{2})$
(2) $(2 m / s^{2})$
(3) $(4 m / s^{2})$
(4) $(0.5 m / s^{2})$
2. A body, starting with some velocity, experiences uniform acceleration. It travels a distance of 20 m in $(5^{\text{th}})$ second and 36 m in $(9^{\text{th}})$ second. The acceleration of the particle (in $(m / s^{2}))$ is
3. A particle starts moving along a straight line with velocity ' $(u)$ ' and a constant acceleration ' $(a)$ ', the initial velocity is
(1) $(1 m / s)$
(2) $(-1 m / s)$
(3) $(2 m / s)$
(4) $(-2 m / s)$

(1) 54 m
(2) 58 m
(3) 60 m
(4) 64 m
