Explain in terms of Newton's laws each of the following: How does beating a rug clean it? How does a hummingbird or a helicopter hover in midair? What are the external forces acting when an automobile is traveling on a level road at a constant speed?
Homework Answers
newtons 1st law explains the 1st question .when we beat the rug we set the rug in motion while the dust particles due to their property of inertia tend to remain at rest (since initially they were at rest),and get separated from the carpet.
By newtons Third law, the bird or humming bird pushes the air downward creates an equal and opposing force pushing the helicopter or bird allowing it to hover.
The net external forces acting are friction, air resistance , normal force from road which cancel out the the driving force provided by engine giving net force zero

Now let's consider forces and Newton's Laws. Discuss the following. A box with a mass of 100 kg is on a frozen lake (no friction). A force of 200 N to the left, and another force of 200 N to the right act on the box. Describe the motion of the box. Also, if a car with a constant speed is turning a level corner, is there a net force acting on the car?

Q1) Please provide brief answers to the following question. Approximately one paragraph for each part ought to be sufficient. (a) According to Newton's third law, when you push on a shopping trolley in the supermarket, the trolley pushes back on you with an equal and opposite force. Explain why it is that you can cause the trolley to move by pushing it, even though these forces are equal and opposite. Your explanation should refer to Newton's laws and all of...
