Subject: Physics Topic: 4. Linear kinematics SubTopic: 4.5 Distance travelled in nth second Test Type: N/A Marks: Time: Date:

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

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) $(1 m / s)$
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 $(15^{\text {th }})$ second is

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