Answer 2

Answer:

the kinetic energy will increase by 21%.

Explanation:

pls make me brainiliest

Formula used: Formula used:  K.E= P2/2m

10/100×P=P/10

P1 =  P+P/10=11P/10

K.E1=(11P/10)22m=121P2/2m×100  K.E1=121/100×P2/2m=121/100 K.E .

121/100 K.E−K.E

  =121 K.E.−100K.E./100  

=21K.E100

21K.E/100K.E×100% 21K.E/100K.E ×100% 21%

Thanks so much for marking me brainliest. It means a lot
