AIPMT PRELIMS 2008 Physics Conservation of Momentum MCQ Question
Type: MCQ-numerical-Medium-Class 11
A shell of mass 200 g is ejected from a gun of mass 4 kg by an explosion that generates 1.05 kJ of energy. The initial velocity of the shell is -
A
40 m/s
B
120 m/s
C
100 m/s
D
80 m/s
Correct Answer
Option C
Detailed Explanation
Using conservation of momentum and energy, the velocity of the shell can be calculated. The energy is converted into kinetic energy of both the gun and the shell.
