The bullet which has the greater speed if two bullets are fired at the sametime if bullets have same kinetic energy and one bullet has twice the mass of other.
b) The one which can do the most work.
Answer to Problem 19P
Solution:a) Second bullet travels with the greatest speed with a factor of
b) Both bullets have the same Kinetic energy, so both bullets can do the same amount of work.
Explanation of Solution
Given:Kinetic energies are same for both the bullets
Mass is twice of other mass
Formula Used:
The kinetic energy of a moving particle is given by
m is the mass of the particle.
v is the velocity of the particle.
Calculations: The kinetic energy of the first bullet is
Here,
The kinetic energy of the second bullet is
Where
Since the kinetic energies are same. Equate both the kinetic energies
We know that
The second bullet travels with the greatest speed with a factor of
b) The kinetic energy of each bullet is converted into work. But here both the bullets have same kinetic energy, so both bullets can do the same amount of work.
Conclusion:a) Second bullet travels with the greatest speed with a factor of
b) Both bullets have the same Kinetic energy, so both bullets can do the same amount of work.
