Case Study Questions on Motion in a Straight Line

Case Study Question 1:

Velocity-Time Graph Interpretation

Passage:
A car starts from rest and accelerates uniformly to a velocity of 20 m/s in 5 seconds. It then continues to move at this velocity for the next 10 seconds, after which it decelerates uniformly and comes to rest in the next 5 seconds. A student plots the velocity-time graph and uses it to find displacement and acceleration at different intervals.

Q1. What is the acceleration during the first 5 seconds?
(a) 4 m/s²
(b) 2 m/s²
(c) 5 m/s²
(d) 10 m/s²

Q2. What is the total displacement during the 20 seconds of motion?
(a) 100 m
(b) 300 m
(c) 400 m
(d) 200 m

Q3. What is the nature of motion during the interval from 5 s to 15 s?
(a) Uniform acceleration
(b) Uniform deceleration
(c) Uniform motion
(d) Non-uniform acceleration

Q4. What is the displacement during the last 5 seconds?
(a) 25 m
(b) 50 m
(c) 75 m
(d) 100 m

Answers:
Q1. (a)
Q2. (c)
Q3. (c)
Q4. (b)

Case Study Question 2:

Analyzing Relative Motion

Passage:
Two students are standing on a straight road. One throws a ball towards the other at 10 m/s, while the second starts walking towards the ball with a speed of 2 m/s at the same time. They are initially 100 m apart. A question is raised: “In how much time will the student catch the ball, assuming straight-line motion and no air resistance?”

Q1. What is the relative speed of approach between the student and the ball?
(a) 10 m/s
(b) 8 m/s
(c) 12 m/s
(d) 2 m/s

Q2. What is the time taken by the student to catch the ball?
(a) 10 s
(b) 12.5 s
(c) 8.33 s
(d) 5 s

Q3. If the ball had been thrown in the opposite direction (away from the student), what would the relative speed be?
(a) 8 m/s
(b) 12 m/s
(c) 10 m/s
(d) 2 m/s

Q4. Which kinematic equation justifies this calculation?
(a) $v=u+a t$
(b) $s=u t+\frac{1}{2} a t^2$
(c) $s=v^2-u^2 / 2 a$
(d) Time $=\frac{\text { Distance }}{\text { Relative Speed }}$

Answers:
Q1. (c)
Q2. (b)
Q3. (a)
Q4. (d)

Case Study Question 3:

Passage:
A physics student drops a ball from the top of a building of height 80 m . Simultaneously, her friend at the ground throws another ball upwards with an initial speed of $20 \mathrm{~m} / \mathrm{s}$. Assuming $g=10 \mathrm{~m} / \mathrm{s}^2$, both balls move along the same straight line path (vertical). They meet at a certain point during motion.

Q1. What is the time at which both balls meet?
(a) 2 s
(b) 3 s
(c) 4 s
(d) 5 s

Q2. What is the distance fallen by the ball dropped from the top till the meeting point?
(a) 20 m
(b) 40 m
(c) 30 m
(d) 60 m

Q3. What is the height from the ground where the two balls meet?
(a) 20 m
(b) 30 m
(c) 40 m
(d) 50 m

Q4. Which concept is best used to solve this?
(a) Uniform circular motion
(b) Kinematics in two dimensions
(c) Relative motion in 1D with uniformly accelerated motion
(d) Conservation of energy

Answers:
Q1. (b)
Q2. (c)
Q3. (d)
Q4. (c)
