1. An uniformly accelerated body travels a distance of 24 m in $5^{th}$ second of its motion and 44 m in $15^{th}$ 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 $5^{th}$ second and 36 m in $9^{th}$ 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) $-2 m/s$
4. A particle starts moving along a straight line with velocity ' $u$ ' and a constant acceleration ' $a$ ', the distance it travels in $15^{th}$ second is
1) 54 m
2) 58 m
3) 60 m
4) 64 m
