MCQ’S on Motion in a Straight Line

Certainly! Here are five multiple-choice questions on motion in a straight line for JEE (Joint Entrance Examination) preparation:

1. An object moves in a straight line with a constant acceleration. If its velocity changes from 10 m/s to 30 m/s in 5 seconds, what is the magnitude of its acceleration?
(a) 4 m/s²
(b) 8 m/s²
(c) 6 m/s²
(d) 2 m/s²

Answer: (a) 4 m/s²

2. A particle starts from rest and moves with a constant acceleration. If it covers a distance of 100 meters in 10 seconds, what is its acceleration?
(a) 5 m/s²
(b) 10 m/s²
(c) 20 m/s²
(d) 50 m/s²

Answer: (b) 10 m/s²

3. The position-time graph of a particle is a curve. What can be said about the motion of the particle?
(a) Uniform motion
(b) Uniformly accelerated motion
(c) Non-uniform motion
(d) Rest

Answer: (c) Non-uniform motion

4. An object is moving in a straight line with an initial velocity of 5 m/s. If it decelerates at a rate of 2 m/s² for 3 seconds, what is its final velocity?
(a) 1 m/s
(b) 2 m/s
(c) 3 m/s
(d) 4 m/s

Answer: (a) 1 m/s

5. A car starts from rest and accelerates uniformly at a rate of 4 m/s². How much time will it take to cover a distance of 100 meters?
(a) 5 seconds
(b) 10 seconds
(c) 25 seconds
(d) 20 seconds

Answer: (b) 10 seconds

Remember to study and practice motion in a straight line concepts thoroughly as part of your JEE preparation. These questions are meant to provide practice and may not cover the entire range of topics in this subject.
