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) $(1 \mathrm{~m} / \mathrm{s}^{2})$
(2) $(2 \mathrm{~m} / \mathrm{s}^{2})$
(3) $(4 \mathrm{~m} / \mathrm{s}^{2})$
(4) $(0.5 \mathrm{~m} / \mathrm{s}^{2})$

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 $(\mathrm{m} / \mathrm{s}^{2})$ ) is

(1) 4
(2) 2
(3) 6
(4) 8

3. A particle starts moving along a straight line with velocity ' $(u)$ ' and a constant acceleration ' $(a)$ ', the initial velocity is

(1) $(1 \mathrm{~m} / \mathrm{s})$
(2) $(-1 \mathrm{~m} / \mathrm{s})$
(3) $(2 \mathrm{~m} / \mathrm{s})$
(4) $(-2 \mathrm{~m} / \mathrm{s})$

4. A particle starts moving along a straight line with velocity ' $(u)$ ' and a constant acceleration ' $(a)$ ', the distance it travels in $(15^{\text {th }})$ second is

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