1.	A body of mass 200g is moving with a velocity of 5m/s. If the velocity of the body changes to 17m/s , calculate the change in linear momentum of the body.
Answer» <U>Given:- ▪︎Mass(m)=200g =>200/1000 =>0.2kg ▪︎Initial VELOCITY(u)=5m/s ▪︎Final velocity(v)=17m/s To find:- ▪︎CHANGE in linear MOMENTUM of the body. Solution:- We know that change in linear momentum of a body is --- =>Final momentum-Initial momentum =>mv-mu =>m(v-u) =>0.2(17-5) =>0.2×12 =>2.4kg m/s Thus,change in linear momentum of the body is 2.4 kgm/s

A body of mass 200g is moving with a velocity of 5m/s. If the velocity of the body changes to 17m/s , calculate the change in linear momentum of the body.

Answer»

▪︎Mass(m)=200g

=>200/1000

=>0.2kg

▪︎Initial VELOCITY(u)=5m/s

▪︎Final velocity(v)=17m/s

▪︎CHANGE in linear MOMENTUM of the body.

We know that change in linear momentum of a body is ---

=>Final momentum-Initial momentum

=>mv-mu

=>m(v-u)

=>0.2(17-5)

=>0.2×12

=>2.4kg m/s

Thus,change in linear momentum of the body is 2.4 kgm/s
