Bsc CSIT Semester 1 – Physics – Unit 1: Rotational Dynamics and Oscillatory Motion (5 Hrs.)

Question 1

An oscillating block of mass 250 g takes 0.15 sec to move between the endpoints of the motion, which are 40 cm apart. $\quad$ (a) What is the frequency of the motion? $\quad$ (b) What is the ampli

Given Data - Mass of block, $ m = 250 \, \text{g} = 0.25 \, \text{kg} $ - Time to move between endpoints = $ 0.15 \, \text{s} $ - Distance between endpoints = \( 40 \, \text{cm} = 0.40 \, \tex

Question 2

Distinguish rigid and non-rigid body. Derive an expression for rotational kinetic energy and discuss the conditions for conservation of energy. A wheel of radius 0.4 m and moment of inertia 1.2 kg-m2,
