Question

pl solve this , its urgent with explanation​

Answer 1

Answer:

300%

Explanation:

ke= p^2/2m

p increased by 100% which means double

thus ke becomes 4 times

increment is 3 times original value thus 300%

Answer 2

let the initial momentum be mv

so,intial kE=1/2 mv^2

new momentum after increasing,by 100percent=mv+mv×100/100

=2mv

since ,mass can't be change ,to increase in momentum, velocity can work....

so,this shows that the velocity become two times

final velocity=2v

new kinetic energy=1/2×m×(2v)^2

=2mv^2

change in kinetic energy=2mv^2-1/2mv^2

=(3/2)mv^2

percentage change={(3/2mv^2)×100}/mv^2/2

=300percent
