Show that lawn roller is easier to pull rather than push

1.	Show that lawn roller is easier to pull rather than push
Answer» When the lawn roller is pulled,\xa0the normal component decreases\xa0that means the cosine component of force decreases. ... This will increase the frictional force. Therefore we can say that it is easier to pull<br>While pulling, by weight we can pull,=netforce=weight-fsinTheta(vertically along x-axis).While pushing, by weight and also force is also applied on that to make it push,=net force=weight+Fsintheta<br>When the lawn roller is pulled, the normal component decreases that means the cosine component of force decreases. ... This will increase the frictional force. Therefore we can say that it is easier to pull the lawn roller than to push it because the normal component of force decreases when the lawn roller is pulled.
