a body of mass 50kg will have more kinetic energy and another body of mass 100kg have equal momentum. Which body will have more kinetic energy?
Answers
hey,
just put 50kg in place of A
and 100kg in place of B
Answer:
A body of mass 50kg will have more kinetic energy than another body of mass100 kg have equal momentum.
Explanation:
Given : The mass of two different bodies are 50kg and 100kg respectively.
To Find ;Which body will have more kinetic energy.
Solution:
K.E for the body having 50 kg mass ⇒K.E=1/2mv^2
=1/2m*m^2v^2
=1/2*50*P^2
P= momentum which is fix for two different bodies.
K.E for the body having 100kg mass⇒ K.E= 1/2mv^2
1/2*m*m^2v^2
=1/2*100 *P^2
As, 1/100P^2 >1/200P^2
So, A body having 50 kg have more kinetic energy.
