Question

Two bodies of equal masses are
moving with uniform velocity in the ratio 1:3 . find the ratio of there kenotic energy​

Answer 1

Answer:

K.E=0.5×m×v  

2

 

K.E(1st)=0.5×m×v  

2

 

K.E(2nd)=0.5×m×(2v)  

2

 

Hence the ratio is 0.5×m×v  

2

:0.5×m×(2v)  

2

=1:4

Hence the ratio is 1:4.
