Explain why easier to pull a lawn roller than to push it?
Explaination:
In Pulling,
effective weight of lawn mover= mg-fsinx
In pushing,
effective weight = mg+fsinx
The force applied to move a body depends upon effective weight. As effective weightin the case of pulling is less than in the pushing , so less force is required in pulling. Hence, it is easier to pull than to push.
