Answer:
No, the lawn mover will maintain the same speed as the person pushing it
Step-by-step explanation:
To understand this, we need to reflect back to the law of motion, the first law to be précised.
It states that "A body will continue to be at rest or uniform/constant motion unless acted upon by an external force which is greater than the current force"
So we can see that since the person continues to apply the same force at the same speed, the effect on the mover will be the same.
