Question

If K.E. of a body increases by 100%. By how much will its momentum
change?

Answer 1

let the ke= 1/2 mvsquare

after increasing it by 100percent

ke = mvsq.

now p= mv

so there are two cases

kinetic energy can be increased by 100 percent by increasing its velocity

or its mass

as ke is directly proportional to square of velocity so we need to specify by changing which quantity the ke has change

unless this it is not calculatable
